Sometimes we want to create an FSM instance before we know its name. In
that case we should be able to update the id later.

Add generic function which allows caller to set Mobile Identity
explicitly. This allows to use IMEI or IMEISV for example. Make
gsm48_generate_mid_from_imsi() into wrapper around new function.

Add wrapper for osmo_strlcpy() which uses sizeof() to automatically
determine buffer's size and use it for GSMTAP logging. This is pretty
common use case for osmo_strlcpy() so it's a good idea to save some
typing by using generic define.

TS 24.007 is quite clear: The upper two bits of the message type
octet are *not* part of the message type in any of the L3 protocols
which implement sequence numbers. it doesn't matter if it's R98 or
R99, or whether the sequence number is 1bit or 2bits wide.

3GPP doesn't specify a network-side T310 default, but waiting for 180s
(3 minutes!) for the next message after CALL CONFIRMED is clearly way
too long and will just use radio resources for no good reason.

In the C API, add another enum log_file_type value, and when set print only the
basename of the source file path.
Rationale: especially when not building directly in the source dir, the paths
to the source files can become rather long. Usually, just the basename of the
file is sufficient to identify the source line.

Add a separate flag and API to switch the category-in-hex output:
log_set_print_category_hex().
Add log_set_print_filename2() to modify only the print_filename flag. The old
log_set_print_filename() function still affects both flags. Explain the
rationale in the comment for log_set_print_filename().
There is no need to deprecate log_set_print_filename(); it might cause compiler
warnings and break strict builds unnecessarily.
Add VTY command 'logging print category-hex (0|1)'.
Since there is no VTY command to switch filename output, nothing needs to be
adjusted there (a command will be added in a subsequent patch).

According to the GSM 04.80 (version 5.0.0) specification Annex A
"Expanded ASN.1 Module "SS-Protocol", the maximum size of a USSD
OCTET STRING is 160 bytes.
Thus according to ETSI TS 123 038 (version 10.0.0) specification
6.1.2.3 "USSD packing of 7 bit characters", in 160 octets, it's
possible to pack (160 * 8) / 7 = 182.8, that is 182 characters.
The remaining 6 bits are set to zero.
This change defines both mentioned values:
- GSM0480_USSD_OCTET_STRING_LEN 160
- GSM0480_USSD_7BIT_STRING_LEN 182
keeping the old MAX_LEN_USSD_STRING 'as is' due to compatibility
reasons. Now the new value is used for ss_request structure, while
old one is still used for deprecated ussd_request structure.

When a bad GSM voice frame is received, it's being replaced
by a silence frame. This may cause unpleasant audio effects.
This change implements a functionality to craft a replacement
frame from the last known good frame. Currently, only FR is
supported, support for other codecs may be added latter.

Add gsm48_encode_ra() which takes appropriate struct as [out] parameter
instead of generic buffer. Using uint8_t buffer instead of proper struct
type prooved to be error-prone - see Coverity CID57877, CID57876.
Old gsm48_construct_ra() is made into tiny wrapper around new
function. The test output is adjusted because of the change in function
return value which was constant and hence ignored anyway.

If a control command fails to parse, we so far discard specific error messages
and instead send just "Command parser error".
In ctrl_cmd_parse() we actually compose detailed error replies, but in the end
simply talloc_free() them and return NULL.
A first step to report these errors to the ctrl command issuer is to not return
NULL and instead return the cmd with type = CTRL_TYPE_ERROR. Add
ctrl_cmd_parse2() to return such instead of NULL.
To stay API compatible, provide ctrl_cmd_parse2() to return a cmd on errors.
ctrl_cmd_parse() retains identical behavior but becomes just a simple wrapper
around ctrl_cmd_parse2() which discards the cmd on error.
No need really to deprecate ctrl_cmd_parse() yet; especially as long as
compiler warnings might break jenkins builds.

To report invalid characters in identifiers, it is desirable to escape any
weird characters. Otherwise we might print stray newlines or control characters
in the log output.
ctrl_test.c already uses a print_escaped() function, which will be replaced by
osmo_escape_str() in a subsequent patch.
control_cmd.c will use osmo_escape_str() to log invalid identifiers.

To send a Ciphering Mode Command, we may need to derive a Kc from UMTS AKA
tokens. gsm_milenage() derives Kc from 3G tokens, but also derives an SRES.
For SRES, it requires an OPC, which may need to be derived from OP first. All
we need is a Kc, so we could feed a zero OPC ... but to simplify the function
call for cases where just a Kc is required, separate the c3 function out from
gsm_milenage(), as osmo_auth_c3(). Obviously call osmo_auth_c3() from
gsm_milenage() (meaning that osmo-hlr's 55.205 derived auc tests still cover
exactly that implementation).

For example encode_auth_info() from gsup.c calls
msgb_tlv_put(msg, iei, 0, NULL)
to put a tag and len with content data following later.
However, this would cause a memcpy() from a NULL pointer, in tlv_put(). Allow
passing NULL and len = 0 for cases like the above:
If val is NULL, use memset(0) instead of memcpy().
If len is zero, do not copy nor memset anything.
Hence make tlv_put() behave in a well-defined and valid way for any and all
input args; no negative fallout is possible from this patch.
Add proper API doc comment.

As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.
In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling: Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.
