I am setting out to refactor various details about logging. To show the effect,
I am first adding this new test to illustrate the exact effects on the various
osmo programs.
Add logging_vty_test.c as a standalone program that simply defines a few
logging categories and opens a telnet vty to play with.
Add logging_vty_test.vty, as an osmo_verify_transcript_vty.py test script.
Add --enable-external-tests to configure.ac, to enable running
logging_vty_test.vty during 'make check'.
Also allow running 'make vty-test' without the need to first configure with
--enable-external-tests (a flexibility I've missed many times over in the other
osmo source trees).
Add a Makefile.am stub for external CTRL tests, basically a copy-paste from
osmo-msc.git. I doubt that libosmocore will get python driven CTRL interface
testing any time soon, but if so we will know to not run it concurrently.

Do not link against the system-wide installed libosmo* libs when building the
regression test programs. Always use the locally built ones.
Linking some libosmo libraries causes libtool to pull in other libosmo libs
even though they were not explicitly named. For example, ctrl_test explicitly
links libosmoctrl, but this also has dependencies to libosmovty and libosmogsm:
ldd src/ctrl/.libs/libosmoctrl.so | grep osmo
libosmocore.so.11 => /usr/local/lib/libosmocore.so.11 (0x00007f26c26d4000)
libosmogsm.so.10 => /usr/local/lib/libosmogsm.so.10 (0x00007f26c22bb000)
libosmovty.so.4 => /usr/local/lib/libosmovty.so.4 (0x00007f26c2171000)
If we omit explicit LDADD of these dependencies in the Makefile.am, libtool
will take the first canonical place to find them, which may just be the already
installed older versions of the same libs, which may or may not be compatible
with the current build. In any case, it is never intended to link installed
libs.
All library dependencies are listed by this quick script:
cd libosmocore
for l in $(find . -name "*.so") ; do echo; echo "$l"; ldd $l | grep libosmo; done

Add all explicit linking of all required library dependencies in all regression
test programs, as shown by above listing.
Example for reproducing a problem:
In libosmocore.a, introduce a new function, and call that from libosmovty code.
For example, I made loglevel_strs non-static in logging.c, and used that in
logging_vty.c. Build and install this in a place where libtool can find it.
Then go back to before this change and rebuild. You will see that linking
ctrl_test (before this patch) then complains about libosmovty requiring the
loglevel_strs symbol which it cannot find in libosmocore.so.

The recent exit-by-indent patch breaks a VTY case where a node is entered but
directly followed by a sibling or ancestor without listing any child nodes.
Regression introduced by I24cbb3f6de111f2d31110c3c484c066f1153aac9.
An example is a common usage in osmo-bts, where 'phy N' / 'instance N' is a
parent node that is commonly left empty:
phy 0
instance 0
bts 0
band 1800
Before this patch, this case produces the error:
There is no such command.
Error occurred during reading the below line:
bts 0
Fix indentation parsing logic in command.c to accomodate this case.
Add a unit test for empty parent node.

Note: This will break users' config files if they do not use consistent
indenting. (see below for a definition of "consistent".)
When reading VTY commands from a file, use indenting as means to implicitly
exit child nodes. Do not look for commands in the parent node implicitly.
The VTY so far implies 'exit' commands if a VTY line cannot be parsed on the
current node, but succeeds on the parent node. That is the mechanism by which
our VTY config files do not need 'exit' at the end of each child node.
We've hit problems with this in the following scenarios, which will show
improved user experience after this patch:
*) When both a parent and its child node have commands with identical names:
cs7 instace 0
point-code 1.2.3
sccp-address osmo-msc
point-code 0.0.1
If I put the parent's command below the child, it is still interpreted in the
context of the child node:
cs7 instace 0
sccp-address osmo-msc
point-code 0.0.1
point-code 1.2.3
Though the indenting lets me assume I am setting the cs7 instance's global PC
to 1.2.3, I'm actually overwriting osmo-msc's PC with 1.2.3 and discarding the
0.0.1.
*) When a software change moves a VTY command from a child to a parent. Say
'timezone' moved from 'bts' to 'network' level:
network
timezone 1 2
Say a user still has an old config file with 'timezone' on the child level:
network
bts 0
timezone 1 2
trx 0
The user would expect an error message that 'timezone' is invalid on the 'bts'
level. Instead, the VTY finds the parent node's 'timezone', steps out of 'bts'
to the 'network' level, and instead says that the 'trx' command does not exist.
Format:
Consistent means that two adjacent indenting lines have the exact
same indenting characters for the common length:
Weird mix if you ask me, but correct and consistent:
ROOT
<space>PARENT
<space><tab><space>CHILD
<space><tab><space><tab><tab>GRANDCHILD
<space><tab><space><tab><tab>GRANDCHILD2
<space>SIBLING
Inconsistent:
ROOT
<space>PARENT
<tab><space>CHILD
<space><space><tab>GRANDCHILD
<space><tab><tab>GRANDCHILD2
<tab>SIBLING
Also, when going back to a parent level, the exact same indenting must be used
as before in that node:
Incorrect:
ROOT
<tab>PARENT
<tab><tab><tab>CHILD
<tab><tab>SIBLING
As not really intended side effect, it is also permitted to indent the entire
file starting from the root level. We could guard against it but there's no
harm:
Correct and consistent:
<tab>ROOT
<tab><tab>PARENT
<tab><tab><tab><tab>CHILD
<tab><tab>SIBLING
Implementation:
Track parent nodes state: whenever a command enters a child node, push a parent
node onto an llist to remember the exact indentation characters used for that
level.
As soon as the first line on a child node is parsed, remember this new
indentation (which must have a longer strlen() than its parent level) to apply
to all remaining child siblings and grandchildren.
If the amount of spaces that indent a following VTY command are less than this
expected indentation, call vty_go_parent() until it matches up.
At any level, if the common length of indentation characters mismatch, abort
parsing in error.
Transitions to child node are spread across VTY implementations and are hard to
change. But transitions to the parent node are all handled by vty_go_parent().
By popping a parent from the list of parents in vty_go_parent(), we can also
detect that a command has changed the node without changing the parent, hence
it must have stepped into a child node, and we can push a parent frame.
The behavior on the interactive telnet VTY remains unchanged.

More osmo-auc-gen invocations could be added, but my main focus is on the SEQ

There are some projects, such as GR-GSM and OsmocomBB, which would
benefit from using one shared implementation of GSM 05.03 code. So,
this commit introduces a new sub-library called libosmocoding, which
(for now) provides GSM, GPRS and EDGE transcoding routines, migrated
from OsmoBTS.
The original GSM 05.03 code from OsmoBTS was relicensed under
GPLv2-or-later with permission of copyright holders (Andreas Eversberg,
Alexander Chemeris and Tom Tsou).
The following data types are currently supported:
- xCCH
- PDTCH (CS 1-4 and MCS 1-9)
- TCH/FR
- TCH/HR
- TCH/AFS
- RCH/AHS
- RACH
- SCH

The write queue was always meant to not queue more than the
max_length messages but the implementation never rejected a
message.
Begin to log and enforce the queue size limit, add a testcase
to verify the code and initialize except_cb as part of a fix
for that new test case.
Real applications might now run into the queue limit and drop
messages where they just queued them before. It is unfortunate
but I still think it is good to implement the routine as it was
intended. We need to review osmo_wqueue_enqueue once more to
see that no msgb is leaked.

Numerous issues caused sim_test to be attempted even though libosmosim was not
built:
In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported.
Furthermore in configure.ac, no value 'yes'/'no' was assigned to the
ENABLE_PCSC variable, only to the enable_pcsc value.
In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have
no effect, regardless (not even when using a variable that should be defined
accurately).
So fix with these steps, similarly to how we do it in openbsc:
In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'.
Export the same using AC_SUBST().
Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add
atlocal to AC_OUTPUT and distclean).
Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to
indicate skipping the test if enable_sim_test isn't 'yes'.

While the bytes in the bitvecs do not need to be aligned, the uint8_t
