743d147d16 SDR: Turn TX power off if requested by network
The power level is ramped smoothly within 1 ms up or down.

R2000, AMPS and C-Netz turn off power when voice channel is not i use.

C-Netz turns off power between OgK timeslots.

2c1ab89723 Notify about usage of channels that are next to each other
It is required to have at least one free channel between channels, to
avoid interferences.
This is only a warning, it will not reject channels next to each other.

0557bbbc43 SDR: Checking given parameters with a tollerance of up to 0.001
Rounding errors may cause given parameters to be changed a little.
When comparing the set-values with the get-value, a small amount
of tollerance must be allowed.

Thanx to Syvain, pointing to this bug!

be used. This width is 2 to the power of N.
