BER-TLV EF support (command, filesystem, shell)
This adds support for a new EF file type: BER-TLV files. They are
different from transparent and linear fixed EFs in that they neither
operate on a byte stream nor fixed-sized records, but on BER-TLV encoded
objects. One can specify a tag value, and the card will return the
entire TLV for that tag.
As indicated in the spec, the magic tag value 0x5C (92) will return a
list of tags existing in the file.
