Harald Welte e61d459cef Support building with -Werror=strict-prototypes / -Werror=old-style-definition
Unfortunately "-std=c99" is not sufficient to make gcc ignore code that
uses constructs of earlier C standards, which were abandoned in C99.

See https://lwn.net/ml/fedora-devel/Y1kvF35WozzGBpc8@redhat.com/ for
some related discussion.

Oliver Smith 04bfb7165b treewide: remove FSF address
Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

Oliver Smith 894be2d9da gsm23003: add osmo_imei_str_valid()
Verify 14 digit and 15 digit IMEI strings. OsmoHLR will use the 14
digit version to check IMEIs before writing them to the DB.

Place the Luhn checksum code in a dedicated osmo_luhn() function, so
it can be used elsewhere.

Neels Hofmeyr 20f7d0ecb4 fix osmo_mnc_from_str(): don't try to parse NULL
In osmo_mnc_from_str() do not try to return some values even if the validation
fails; hence don't try to decode a NULL pointer. That whole idea was half-baked
and a can of worms to begin with.

Neels Hofmeyr 5b8b8c62b4 gsm23003_test: fix: compare members instead of bcmp
In certain builds (for me a build with no -O2 flag) the recently added
gsm23003_test test_mnc_from_str() fails, because bcmp() compares all bytes of
sizeof(struct test_mnc_from_str_result), which has valid data for 7 bytes plus
one padding byte that may contain arbitrary values. Instead of bcmp(), rather
compare the actual members one by one.

Neels Hofmeyr 721aa6ded9 gsm: add osmo_mnc_from_str(), osmo_mnc_cmp(), osmo_plmn_cmp() for 3-digit MNC
osmo_mnc_from_str() preserves leading zeros in the string and is useful for
VTY config parsing (osmo-bsc, osmo-msc, osmo-sgsn, osmo-pcu).

osmo_{plmn,mnc}_cmp() takes care of the slight intricacy of ignoring the 3-digit flag
if the MNC is anyway >99. Will be used by osmo-sgsn.git and osmo-bsc.git.  (All
current users just care about identical MNC, but a proper cmp doesn't hurt.)

Neels Hofmeyr 4b7c791e15 gsm: make osmo_imsi_str_valid() NULL-safe
No callers that would pass NULL exist, but let's check against NULL from the
start.

Fixup for recent change I1e94f5b0717b947d2a7a7d36bacdf04a75cb3522.

Neels Hofmeyr 9cd1e7417e add osmo_imsi_str_valid() and osmo_msisdn_str_valid()
Add GSM23003_IMSI_MIN_DIGITS definition.
Add regression test gsm23003_test.c to test the two new functions.

Will be used by OsmoHLR to validate VTY and CTRL input.
