KongQun Yang 9a55d4033f Adjust timestamps in mp4 if there is an initial composition offset
In some ISO-BMFF files, there is an initial non-zero composition offset,
but there is no EditList present.

This is against ISO-BMFF spec recommentation [1] and we believe in most
cases it is just missing the EditList.

[1] 14496-12:2015 8.6.6.1
It is recommended that such an edit be used to establish a presentation
time of 0 for the first presented sample, when composition offsets are
used.

Issue: #112.
Fixes: b/110782437.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
Seeing some failures on some platforms when compiled with clang
disabled:
  GYP_DEFINES="clang=0" gclient runhooks

Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
   all linux distributions.

Fixes #286
Fixes #293

KongQun Yang 0218d9c690 Move fourccs.h and rcheck.h to media/base
- FOURCC is not a mp4 only concept. It is also used elsewhere.
- RCHECK has been used outside formats/mp4.

Also updated the FOURCC enum names to match the actual fourcc code, e.g.
FOURCC_mdat for "mdat".

Jacob Trimble 96abd90ca2 Only encrypt video slice NAL units.
For non-video slices, the data is not encrypted.  This also skips the
frame headers for H.264; support for H.265 will be added later.

Anders Hasselqvist db7bebe3fa MacOSX: Solve libbase.a conflict link error
On Linux the generated ninja files use path/libbase.a as target name.
In the Mac ninja file the target is just libbase.a.
As we have two libbase.a (base/base.gyp and media/base/media_base.gyp) the linking stage fails to include both libs.

Solve by renaming media_base.gyp's base target to media_base
