http: add hack to make streams served by MediaGateway not seekable

These streams are reported as seekable, but all tests show they are not,
and the server merely pretends the streams are seekable. The server
responds with:

    content-range: bytes 0-1999999999/2000000000

Range requests seem to be correctly answered, but the actual data
returned at the same offset is different. Assume this is a bug in the
server software. The server identifies itself as:

    Server: MediaGateway 3.5.2-001

Add a hack that checks the server name, and disables seeking in this
case.

avcodec/x86/hpeldsp: fix crash on AMD K6-3+

There are instructions pavgb and pavgusb. Both instructions do the same
operation but they have different enconding. Pavgb exists in SSE (or
MMXEXT) instruction set and pavgusb exists in 3D-NOW instruction set.

livavcodec uses the macro PAVGB to select the proper instruction. However,
the function avg_pixels8_xy2 doesn't use this macro, it uses pavgb
directly.

As a consequence, the function avg_pixels8_xy2 crashes on AMD K6-2 and
K6-3 processors, because they have pavgusb, but not pavgb.

This bug seems to be introduced by commit

x86: vp8dsp: Split loopfilter code into a separate file

configure: Properly check for availability of -Wno-foo warning flags

For some weird reason gcc does not check if the -Wno disabling variants
of warning flags match existing warning flags. Instead it swallows them
silently. That is, unless other warning or error messages are generated,
because then - for some even more bizarre reason - a complaint about the
unknown disable warning flag is issued along with the error or warning
message.

Thus to check for the availability of a warning disabling option, one
needs to check for the enabling variant instead and then add the
disabling variant to CFLAGS.

configure: Split test_cflags function off from check_cflags

This is useful to test flags without directly adding them to CFLAGS.
