Remove all global variables in P1 dissector. Bug 8515 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8515)

Added a "subtree context" structure to asn1_ctx_t. This should allow other ASN.1 dissector global variables to be replaced when only used for transferring data between fields in a subtree.
