gsm48: move to hex TMSI representation
Previously, we traditionally displayed a TMSI in its integer representation, which is quite unusual in the telecom world. A TMSI is normally printed as a series of 8 hex digits.

PS1, Line 461: It is not a "reverse" anymore. Should the comment be updated? Specially with gsm48_generate_mid_from_tmsi just taking the uint32?
PS1, Line 465: string Why do you prefix it with 0x here? In the commit message I would like to have a small statement about the minimum size of the "string" not having.
Who consumes the result and does the represntation matter?

Because I saw that the 0x%08x format also used in other Osmocom projects, for example in OsmocomBB. Well, the minimum ant the maximum size of the string is always constant and equal to 2 + 8 = 10 (without '\0').
It is mostly consumed by user, so I think we should use the most comfortable for reading format.
Would you prefer to avoid the '0x' prefix in this case? Also, what about using '%08X' instead of '%08x'?

I think the general representation in the industry would be all-uppercase and without 0x, so "%08X". However, as we used to have integer representation in OpenBSC so far, it might be a good idea to give the '0x' as a hint to the user, so he knows this version of the log statement/vty output is in hex, as opposed to earlier versions.
