1b3dbe3f75 lcldec: fix decoding of uncompressed rgb24 sample
Sample from ticket #1216 does not use any compression but bitstream
claims it is. Reference decoder decodes sample just fine.

Fixes #1216.

01cb62aba2 lcl: don't overwrite input memory.
If the PNG filter is enabled, a PNG-style filter will run over the
input buffer, writing into the buffer. Therefore, if no zlib compression
was used, ensure that we copy into a temporary buffer, otherwise we
overwrite user-provided input data.

e7e2df27f8 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as
hidden.

b34aaed2cf Move #ifdef before zlib_decomp() up so it covers the Doxygen comments.
Otherwise Doxygen gets confused and cannot map comments to functions.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

int8_t, not uint8_t to allow -1 for "no compression".
The original code worked, but only when char was signed.
