Other helpers can be implemented as trivial wrappers over existing tlv.h

Completely drop the implementations of log_vty_command_{str,description}().
These functions have been public API once, marked as deprecated since
c65c5b4ea0 (March 2017). I considered to keep
them, or reduce them to useless stubs, but it is quite silly, really. These
functions are completely and utterly useless outside of libosmocore. Any
program linking these deserves to fail.
Re-implement vty logging level command gen, in logging_vty.c. logging.c is
simply the wrong place for that.
Introduce logging_internal.h to share logging definitions to logging_vty.c
without publishing as API.
Introduce static gen_logging_level_cmd_strs() to compose a list of category
arguments with their descriptions for VTY commands. Use osmo_talloc_asprintf()
instead of the previous error prone and chaotic strlen() counting method.
Do not dynamically generate log level arguments, just keep static strings. We
are super unlikely to ever change the log levels we have.
No changes in logging_vty_test.vty: proves that there is no functional change.
All of this, besides introducing basic sanity, is cosmetic preparation to be
able to re-use the generic command generation code for arbitrary commands with
category or level args (for deprecated and new keywords).
Rationale: I want to hide 'all' and 'everything' from the VTY command
documentation, by means of deprecating. I first tried to simply define a
deprecated 'logging level CAT everything' command:
logging level (all|rsl|rr|...) (debug|info|notice|error|fatal)
logging level CAT everything # <- deprecated and hidden
But unfortunately, command matching doesn't work as intended when the CAT
argument reflects a valid category; I want it to invoke the deprecated function
as soon as the 'everything' keyword follows, but it stays stuck to the "valid"
command when the category argument matches an explicit keyword in that list,
and will throw an error on the following 'everything' keyword. I.e.:
logging level rsl everything
% Unknown command # <-- leads to config file parse error
logging level unknown_string everything
% Ignoring deprecated 'everything' # <-- works only for invalid categories
So I need to define 'everything' separately, again with a list of each valid
category instead of a generic CAT arg.

We already have osmo_str2lower() and osmo_str2upper(), but these lack:
* proper destination buffer bounds checking,
* ability to call directly as printf() argument.
Deprecate osmo_str2upper() and osmo_str2lower() because of missing bounds
checking.
Introduce osmo_str_tolower_buf(), osmo_str_toupper_buf() to provide
bounds-safe conversion, also able to safely convert a buffer in-place.
Introduce osmo_str_tolower(), osmo_str_toupper() that call the above _buf()
equivalents using a static buffer[128] and returning the resulting string
directly, convenient for direct printing. Possibly truncated but always safe.
Add unit tests to utils_test.c.
Replace all libosmocore uses of now deprecated osmo_str2lower().
Naming: the ctype.h API is called tolower() and toupper(), so just prepend
'osmo_str_' and don't separate 'to_lower'.

Allow printing the source file information *after* the log information.
Add target->print_filename_pos, log_set_print_filename_pos() and enum
log_filename_pos, and the optional 'last' keyword to the 'logging print file'
vty command. (An enum in case we want to add other positions later.)
Rationale: on log lines, the logging context is usually printed first in the
logging text. Without the source file information, this logging context pretty
much aligns in an easily readable way. When adding the source file information,
each line's logging context info is shifted right by a pretty much random
amount and it is hard to spot recurring logging contexts.
One solution is to switch off source file info, of course, but that's not an
option when actively hacking on bugs and new features.
For example, it is unnecessarily hard to spot lchan FSM related log lines in
this osmo-bsc log snippet:

When IPPROTO_UDP is used then SO_REUSEADDR omitted since UDP is
connection less we do not have to wait until lingering connections time
out. There were also negative effects such as that two applicatications
could use the same UDP port, normally one of the two applications would
get an error, but with SO_REUSEADDR this is supressed. However, there
are applications (UDP MULTICAST) where two applications must be able to
use the same port. In the osmocom project those are osmo-bts-virtual,
virtphy and gsmtap in general.
Lets introduce a flag that the API user can supply in order to have
SO_REUSEADDR applied.

The intention was to use the file's basename, but __BASE_FILE__ means "the root
file that is being parsed and contains #include statements".
If we had a function using __BASE_FILE__ and that was defined in an #included
file, __BASE_FILE__ would indicate the first file where the #include is, and
not the file where the function is defined. __BASE_FILE__ works for us because
we don't ever include function definitions that log something, so __BASE_FILE__
always coincides with __FILE__ for our logging; but still __BASE_FILE__ is
semantically the wrong constant.

In the past, the function ipa_ccm_idtag_parse() was used to parse
the payload of IPA CCM ID RESP packets. However, the function was
based on a possible misunderstanding of the message encoding, and
callers actually counted the first (upper) length nibble as part
of the header and passed a pointer to the second
(lower) length nibble of the first TLV into this function. As such,
it was unfixable, and had to be replaced with a new function called
ipa_ccm_id_resp_parse(). At the same time, we also add
ipa_ccm_id_get_parse() to parse the slightly different format of
the IPA CCM ID GET payload.
We can never be 100% sure what is "correct", as our understanding
of the protocol is entirely based on protocol analysis, without any
official documentation available.
This patch also introduces unit test coverage for both of the new
functions.

Revert "ipa: Properly parse LV stream of a ID_GET request"

It introduced a function/behavior that was not originally intended:
The parse of IPA CCM ID GET (8bit length followed by 1 byte tag
and variable-length payload) instead of the IPA CCM ID RESP (16bit
length followed by 1 byte tag and variable-length payload).
