bts: Allow config of RACH control parameters tx-integer & max retrans

Tweaking theses can be useful especially tx-integer that influence
both the spread of rach attemps and the delay between two attemps.

Looking up GSM 04.08 3.3.1.1.2 & 10.5.2.29 can help determine good
values. The default are choosed with a wide spacing between attemps
(tx integer = 9 -> T=12 & S=217 (non-combined CCCH/SDCCH) or 115 (for
combined CCCH/SDCCH)). This alleviates the problem of responding to
several RACH attempts by a same MS, allocating several RF channels when
only 1 is needed.
