Harald Welte fbd02fa8cc tlv: Import osmo_shift_* and osmo_match_shift_* from openbsc 
These routines have nothing to do with specifically the BSC, so import
them to the TLV parser we keep in libosmogsm.

Andreas Eversberg 0167596c2b Add tlvp_val16_unal() / tlvp_val32_unal() to align 16 and 32 bit values 
This is required for CPUs < armv6, to access 16 and 32 values at right
memory locations.

Harald Welte 2fe684755a TLV: add new "vTvLV" type for GAN 
This new TLV type is specific to TS 44.318.  Contrary to the TvLV type
of TS 08.16/08.18, it has an inverted meaning of the extension (0x80)
bit:
	* if the extension bit is not set, 1-byte length
	* if the extension bit is set, 2-byte length

Futhermore, it has support for variable-length tags, where the tag part
can be optionally two bytes in length.  As this esoteric option hasn't
been seen in the wild yet, we only add encoding support but skip
decoding for now.

Harald Welte 2c02043f49 TLV/msgb: Return first byte of newly-pushed data from msgb_*_push() 
The msgb_*_push() functions erroneously returned the firsrt byte after
newly-pushed information, which makes no sense at all.

Thanks to Alexander Huemer for detecting it

Harald Welte 79599ba0eb tlv: Make tlv parser arrays 256 entries wide to prevent overflow on 0xff 
If we encounter a tag with 0xFF, we overflow our existing tlv_parse
array definitions.

Warning: this breaks ABI

Pablo Neira Ayuso 8341934844 include: reorganize headers file to include/osmocom/[gsm|core] 
This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.

This has been proposed by Harald Welte and Sylvain Munaunt.

Tested with `make distcheck'.
