Allow dumping the VTY XML reference (for generating manuals) to a normal FILE*
stream instead of a vty output buffer.
We currently generate the VTY reference by starting the client program,
connecting to the VTY telnet and dumping the reference. That is weirdly
convoluted, especially since there has to be a valid config file that
successfully starts up a minimal set of external links before the reference can
be generated. IMO we should have dumped the XML reference to stdout from the
start, and never to a VTY session.
With this patch, it is trivial to generate the XML VTY reference by a
commandline switch. The client program will set up the entire VTY, and
immediately after parsing the cmdline options but before parsing a config file,
just dumps the reference and doesn't even start establishing local ports. That
would allow generating the XML reference on the fly during the build process of
the manuals, without the need of a docker container or somesuch.
A first implementation of such a commandline switch is `osmo-bsc -X`, added in
I316efedb2c1652791434ecf14a1e261367cd2fb7
This patch jumps through a bit of a hoop to still allow dumping to a VTY buffer
without code dup, to still allow dumping the XML reference through telnet VTY,
until all our programs have implemented an -X switch (TM).

gsm48_pag_resp and gsm48_service_request: omit comments in big endian part.
dtap_header: better segment the substruct.
gsm23041_msg_param_gsm: match up whitespace / comments.
Rationale: the script is a good way to avoid bugs from manually composing the
big endian parts (for example, it detected the missing endian.h include, fixed
in I593cc5e8272469b570559206bb02b6e79797340b). However, it becomes cumbersome
if it creates numerous edits in the source tree, which cause more time spent
for whoever wanted to rather save time with it. So let's keep the code tree
matching that struct's output.

when the API user of libosmocores logging infrastructure does not set a
pre-defined logging level in struct log_info_cat, the result would be an
invalid logging level. In order to avoid problems with that and to spare
all the additional .loglevel = LOGL_NOTICE (API users are advised to use
LOGL_NOTICE as default) lines in the user code lets check the logging
level on startup and set LOGL_NOTICE if there is no logging level set.

In commit [1], the automatic little-to-big-endian compatibility by
struct_endianness.py introduced doubled little/big endian struct listings by
accident, resulting in a wrong big endian structure (due to double reversal in
the original big endian part). Remove the old conditionals around the new
automatic ones to fix the structs for big endian.

while skipping `0` might be visually pleasant for non-repeating groups, e.g.:

So far we only looked at SW definitions of the card profile. However,

that application for SW definitions.
This breaks ABI and API all over the place, but as there are no

AC_SEARCH_LIBS was finding the function correctly, but later on
AC_CHECK_FUNCS was not including the found LIBRARY_RT so the function
was not found, and hence HAVE_CLOCK_GETTIME ended up undefined (which in
turns disables support for osmo_clock_gettime() API).
This happened in systems like the soekris where the clock_gettime sybmol
is available in external lib -lrt.
Let's avoid double-checking for the function twice, and simply define
HAVE_CLOCK_GETTIME when AC_SEARCH_LIBS succeeds (the success action is
guaranteed to be called even if there's no extra lib required).

When switching the l2 structures passes to test_pdtch() to be constant,
it was noted that output of the test changes. This happens because same
array is tested several times with different length, incrementing each
time. Since the test was modifying the input array directly, it means
each new run of test_pdtch() the array was further modified.
Upon constifying the structures, we copy the array and hence only modify
the required bits each time.

As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all.
For those builds LD shoud be set to clang too (and LDFLAGS needs the
sanitizer flags as well), because the clang compiler driver knows how
linking to the sanitizer libs works, but then at a later stage libtool
fails to actually produce the shared libraries and the build fails. This
is fixed by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan'
export CC=clang-10
ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`)
export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"
