beos/mov/adpcm patch by François Revol <revol at free dot fr>

* Some BeOS fixes:
- errno stuff
- nanosleep() replacement
- added a doc/README.beos

* mov reader still has problems with most videos (skips many chunks),
- It should now read .mov files with zlib-compressed moov headers (aka cmov)
- added SVQ1 support.
- removed mapping 'raw ' and 'yuv2' to h263, was my mistake.
- added IMA4 support. (tested)
- fixed frame rate (it reported 0 fps or something before)
- extended file probing ('wide' and 'free' atoms)
- improved .mov/.mp4 detection (or so I think)

* adpcm
* added zlib support, with header file and lib check

+Compilation on BeOS:
+--------------------
+
+François Revol - revol@free.fr - July 2002
+
+The configure script should guess the configuration itself.
+Networking support is currently not finished.
+errno issues fixed by Andrew Bachmann.
+
+Old stuff:
+
+François Revol - revol@free.fr - April 2002
+
+The configure script should guess the configuration itself, 
+however I still didn't tested building on net_server version of BeOS.
+
+ffserver is broken (needs poll() implementation).
+
+There is still issues with errno codes, which are negative in BeOs, and
+that ffmpeg negates when returning. This ends up turning errors into 
+valid results, then crashes.
+(To be fixed)
