This fixes a lot of warnings of the sort:
libavcodec/pcm.c:105: warning: cast discards qualifiers from pointer target type

Use the correct error codes and format identifier.

They've accumulated enough new APIs and corresponding deprecated cruft.

This breaks API and ABI.

The number of dba segments is the coded value + 1.
The coupling dba offset starts at the first coupling band, not at zero.

PROFILE_ADVANCED doesn't set res_fasttx, so make that a special case
in the condition that decides which IDCT to use (and whether to read
coefficients transposed or not).

IDCT coefficients are read transposed, but simple_idct does not expect
this. Therefore, only do tranposed coefficient reading if we're not
using simple_idct.

DTX, discontinuous transmission, allows emitting frames with

Also rename the incorrectly named enc_bitrate to enc_mode, use the
enc_bitrate variable for storing the last chosen bitrate.

This avoids continuous warning log messages if not using an
exactly matching bitrate, while still allowing changing bitrate
at any point.

Dynamically print the supported bitrates from the local table,

Include VisualOn to clarify the codec name, but remove the
actual library name from the user-friendly description.
Also mention Android, to clarify which VisualOn implementation
this refers to, since they do sell other variants of the same
code, too.

(1<<31) is undefined and seems to be evaluated by gcc to -2^31 when
these formulae require 2^31.

These conversions still need fate tests.

According to ISO 9899:1999 S 6.5.7/4:

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.

The wrapper code is based on the libamr wrapper removed in SVN rev 19365.
