Many moz.build files define things that could be defined in parent
moz.build files. Keeping the number of moz.build files low helps with
build times due to less I/O and fewer directories traversed.
This patch eliminates a lot of moz.build files by moving their content
into parent moz.build files.

Previous code didn't adjust bitrate and scale factors correctly
for computing frame sizes on mpeg 2 and 2.5 files. See
http://blog.coryhill.net/2009/06/calculating-mp3-frame-length.html
for the extra factor of two.
Removes a case for handling length calculation for layer-1 files,
which we don't support.
Adds a tagless mpeg-2 test case for the new sniffer code.

Attempt to sniff raw mp3 with no id3 tag by looking for a header
followed by a second header at the expected offset from the packet
length.
Adds mp3 sniffing with and without id3 tags to the mediasniffer
xpcshell tests. These files are truncated to 512 bytes. Our method
can require up to 1.5k of data, but these have 208/209 byte packets
so sniffing still works.
notags-bad.mp3 has a corrupt header, and verifies sniffing fails.
notags-scan.mp3 has garbage before the header, and verifies sniffing fails.
he_free.mp is a vbr test vector which isn't sniffable with this method.
fl10.mp2 is an mp2 file, and verifies sniffing fails.
ff-inst.exe verifies bug 875769 doesn't regress.

Adds mp3 sniffing with and without id3 tags to the mediasniffer
xpcshell tests. These files are copies of files in content/media/test
truncated to 512 bytes. Our method can require up to 1.5k of data,
but these have 208/209 byte packets so sniffing still works.
