The function dump_picture_info() has extra braces in the profiles
HEVC_MAIN_444 and VP9. Because of this, the additoinal braces are
added in the trace file generated by the applications like ffmpeg,
mplayer and so on. The client of this generated trace file, like
the python scripts that read this trace file, run into into the
problem of wrongly reading the picture info or incomplete reading
of picture info.
Also, there was a comma missing in the VP9 profile in the
dump_picture_info(). This again creates the problem of generating
a trace file without a comma, which again leads to wrongly reading
the picture info.
To avoid this problem of wrongly reading or incomplete reading of
picture info, extra braces have been removed and an additional
comma is introduced in the dump_picture_info().

This patch is in response to the following security vulnerabilities
(CVEs) reported to NVIDIA against libvdpau:
CVE-2015-5198
CVE-2015-5199
CVE-2015-5200
To address these CVEs, this patch:
- replaces all uses of getenv(3) with secure_getenv(3);
- uses secure_getenv(3) when available, with a fallback option;
- protects VDPAU_DRIVER against directory traversal by checking for '/'
On platforms where secure_getenv(3) is not available, the C preprocessor
will print a warning at compile time. Then, a preprocessor macro will
replace secure_getenv(3) with our getenv_wrapper(), which utilizes the check:
getuid() == geteuid() && getgid() == getegid()
See getuid(2) and getgid(2) for further details.

The following three were never a part of the public API and as such
should have never been exported by libvdpau_trace.so
Correct that by marking them as static, thus allowing the compiler
to hide them from the exported namespace.
_vdp_cap_init_planes_adapt_surface_video
_vdp_cap_init_planes_adapt_surface_bitmap
_vdp_cap_init_planes_adapt_surface_output

Nothing actually uses VdpPoint, so this tracing function was never called. I
left the VdpPoint type in vdpau.h for now, just in case anyone actually uses it
themselves.

Add profiles for MPEG-4 part 2, DivX 4, and DivX 5. Also add new high quality
scaling options.
