polarssl: added missing end-of-comment from previous commit
polarssl: drop use of 1.2 compatibility header.

API has changed since version 1.3. A compatibility header has been created
to ensure forward compatibility for code using old API:
 * x509 certificate structure has been renamed to from x509_cert to
   x509_crt
 * new dedicated setter for RSA certificates ssl_set_own_cert_rsa,
   ssl_set_own_cert is for generic keys
 * ssl_default_ciphersuites has been replaced by function
   ssl_list_ciphersuites()

This patch drops the use of the compatibly header.
polarssl: break compatibility with version older than 1.3.

Remove all #ifdef/else/endif macros that ensure compatibility with polarssl
version previous than 1.3.
polarssl: fix possible handshake timeout issue in multi.

Because of the socket is unblocking, PolarSSL does need call to getsock to
get the action to perform in multi environment.

In some cases, it might happen we have not received yet all data to perform
the handshake. ssh_handshake returns POLARSSL_ERR_NET_WANT_READ, the state
is updated but because of the getsock has not the proper #define macro to,
the library never prevents to select socket for input thus the socket will
never be awaken when last data is available. Thus it leads to timeout.

trynextip: don't store 'ai' on failed connects...

It leads to the "next family" tries starting from the wrong point and thus
fails!

RELEASE-NOTES: fixed typo
runtests.pl: verify specified test cases

To better allow arguments like "1 to 9999" without flooding the terminal
with error messages, the given test cases range is now checked and only
test numbers with existing files are actually run.
rtsp: parse "Session:" header properly

The parser skipped the initial letter, which presumably often is
whitespace but doesn't have to be.

polarssl: avoid extra newlines in debug messages

The debug messages printed inside PolarSSL always seems to end with a
newline. So 'infof()' should not add one. Besides the trace 'line'
should be 'const'.
tool_getparam: Removed "dead assignment" code introduced in commit 1a9b58fc
tool_parsecfg: Reworked error handling from commit fc59a9e1
tool_operate: Fixed uninitialised variable under some error situations

For example when a URL is not specified or the headers file fails to
open.
