configure: Clearly state that MSYS native builds are discouraged
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
MSYS, as per cygwin, by default uses a custom posix abstraction
in the form of a "msys2.dll". Programs build that way are harder to
distribute and use.
MSYS2 provides alternate launcher scripts that provide a MINGW
environment nearly out of box.
It is known that the naive sqrt(x*x + y*y) approach for computing the
hypotenuse suffers from overflow and accuracy issues, see e.g
http://www.johndcook.com/blog/2010/06/02/whats-so-hard-about-finding-a-hypotenuse/.
This adds hypot support to FFmpeg, a C99 function.
On platforms without hypot, this patch does a reaonable workaround, that
although not as accurate as GNU libm, is readable and does not suffer
from the overflow issue. Improvements can be made separately.

This implementation does not support TLS listen sockets and loading
CA/Certs from files.
The Windows API does not support loading PEM certs, and would either
require a manual loader or instead be limited to loading Windows PFX
certificates
TLS listen sockets would have to be implemented quite separately, as many
of the APIs are different for server-mode (as opposed to client mode).

Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
In order to load libraries in Android they need to be unversioned.
The android target section was derived from the BSD ones, and they
that simply drop the SONAME
Android M requires to have a SONAME entry but unversioned.
Some systems may be lacking getservbyport; the previous ifdef wasn't
quite enough since it still assumed that struct servent was defined,
as pointed out by Clément Gregoire.
Simply remove the possibility to return non-numeric services in
getnameinfo; no caller of getnameinfo within libavformat
currently try to use getnameinfo for retrieving the port number without
NI_NUMERICSERV, and falling back on getservbyport may be non-threadsafe.

This silences warnings like this one:
libavformat/file.c(62) : warning C4996: 'read': The POSIX name for this

GCC (and Clang) have this useful warning that is not enabled by -Wall or
-Wextra. This will ensure that issues like those fixed in
4da52e3630
will trigger warnings.

Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

The versioning facility in the Solaris linker differs from Linux in 3 ways:
1. It does not support globs in linker scripts for
symbol versioning -- this is a GNU extension.
2. The linker argument is '-M', instead of '--version-script'.
3. It is picky about line endings.
Each symbol or directive must be on a line of it's own.
Let's use make_sunver.pl from GCC to generate a version script that works
correctly with the Solaris linker. It's function is to correctly expand the
globs in the original generated version script.

configure: When disabling a library disable all the related components
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
When trying to build the binary dct-test under MSYS2/Win64, the
makefile rule does not have the SUBDIR in the target for its
object file.
Consequently, modifications to various include files (e.g. C ones)
do not trigger a recompilation.
When tracing the dependency generating, the dependency generation
has this strange content (linebreak inserted):
sed -e "/^#.*/d" -e "s,^[[:space:]]*dct\\.o,libavcodec/dct.o," \
> libavcodec/dct-test.d
For some reason, the $(*F) has weird content. It looks simpler to
use $(@F) instead of $(*F)\\.o, although this was tested on one
single version of make.

This way is sufficient to use the component specific configure variable
and not guard against the global library configure variable in code
that is outside it (e.g. checkasm).
Currently, errors are thrown for various macros while building that are completely bogus.
They occur during the dependency (.d) generation phase, and have no bearing on the compiled output,
since only the stdout is piped into the sed command to generate the .d files.
They basically occur as the relevant -I paths are not (and cannot be passed) during
the dependancy generation phase.
As such, this patch silences them.
