Andreas Eversberg a6bf66ee83 POCSAG: Remove unused "repeat" function 
A message can be repeated, but not in that short time of a few seconds.

Pagers may ignore messages if they are received again. The user may
repeat the message, but not the transceiver.

Andreas Eversberg f391c0d947 POCSAG: Allow all 128 ASCII characters to be transmitted 
To allow all 128 ASCII characters, a null-terminated string cannot be
used. Instead a length is used to define string length, to allow
null-character in that the message string.

The print function in frame.c is improved and used to present the
string.

Andreas Eversberg f294261285 Fix filter of demodulator of received radio signal 
The filter was way too low. (only half of the total bandwidth)
The missing (filtered) high frequency component caused noisy signal.
Let's see how this fix changes the quality of received FM sound.

Andreas Eversberg 470fc49341 C-Netz SIM: Fix entering card numbers with leading zeroes 
Numbers for the SIM card can be entered with zeroes in the front. This
will not change numbers to octal. The Bosch OF 7 phone will not accept
numbers in the phone book with less than 4 digits, so it is essential to
allow entering numbers with zeroes in front.

Also state that in the documents.

repeating audio.

This is required if multiple SDP responses are returned. We don't want
to remove a codec with with the first SDP response, which might get
accepted by the second SDP response. Instead we flag the codec as
negotiated or not negotiated.

When early media is received, different codecs may be accepted as when
we receive the actual answer.

Andreas Eversberg fd3b4dae50 FSK modulator improvements 
1. Phase is now changed proportional to the time of the bit change, if
   it happens somewhere between samples. The amount of phase change per
   bit is now the same for all bits, no matter how many samples
   currently lay inside this bit.

2. IIR filter is removed, because it causes distortions. A cosine shape
   is now used to transit between phase change of F0 to F1 and vice
   versa. This limits the spectrum. This filter is optional.

Andreas Eversberg aadfd50a0f Osmo-CC: Change UPDATE to MODIFY message 
Naming it UPDATE was not a good idea.

Now this is renamed to MODIFY message, related to MNCC (GSM). It is used
to change media coding during a call. It allows new codec negotiation
using SDP protocol and/or changing RTP peer. Also useful for SIP.

A reset function allows to clear the decoder states, to prevent glitches
when re-attaching to an interrupted stream.
