  tls: Add options for verifying the peer certificate

Conflicts:
	doc/protocols.texi
	libavformat/tls.c
	libavformat/version.h

See: b2460858
See: 973a758fMerged-by: Michael Niedermayer <michaelni@gmx.at>

A file containing the trusted CA certificates needs to be
supplied via the ca_file AVOption, unless the TLS library
has got a system default file/database set up.

This doesn't check the hostname of the peer certificate with
openssl, which requires a non-trivial piece of code for
manually matching the desired hostname to the string provided
by the certificate, not provided as a library function.

That is, with openssl, this only validates that the received
certificate is signed with the right CA, but not that it is
the actual server we think we're talking to.

Verification is still disabled by default since we can't count
on a proper CA database existing at all times.
