This adds a full identification probe of CC, AS, LD and HOSTCC,
and sets up correct flags and dependency tracking for each.

The rtmpts protocol uses https implicitly, via the ffrtmphttp
protocol, but the ffrtmphttp protocol is also useable for plain
rtmpt without https, so the dependency needs to be added here instead.

This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPE protocol implementation uses ffrtmpcrypt:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.

Use compiler-specific replacements for the -o flag in check_cc.
This makes tests work properly with compilers using non-standard
flags.

The tms470 flags are updated to work with this scheme.

The incompatibility with librtmp is already expressed in the ffrtmphttp
protocol dependency declaration, which both RTMPT and RTMPTS depend on.

This is more consistent, and doing it earlier is harmless.

This allows filtering of linker flags the same was as already
supported for CFLAGS.  The filter must be initialised to 'echo'
early since it is invoked by --extra-ldflags.

Name variables pertaining to various types of flags with 'cflags' etc
as prefix instead of suffix.

This is not used and the current design would not work properly
if mixing tools needing different filters.

This variable is only used once, so setting it there is clearer.

This is only used for checking for a certain library, but the code
doesn't need to know whether the function was found.

Signed-off-by: Martin Storsjö <martin@martin.st>

The actual result of the check isn't used anywhere (since we
use this function unconditionally within #ifdef _WIN32), but it
makes sure we explicitly link to shell32 (which is linked in
implictly on mingw).

This function is only available in the headers if unconditionally
targeting a version >= XP. It is not strictly necessary, since we
try loading these functions dynamically at runtime on windows in
the fallback, but this makes things a bit faster and more
straightforward.

On mingw32, this function isn't visible by default, while it is
on mingw64 (on both 32 and 64 bit).

The mxf_d10 test depends on avconv, which depends on avfilter, so there
is no need to declare an avfilter dependency for the mxf_d10 test.
