Avoids mistakes by making sure everyone allocates these the same
way.
The smart card code still has manual allocation because it has it's
own magical memory management.

We were using the incorrect type for the context for these two calls.
No practical effects, but some noise from the compiler about the wrong
pointer type.
This commit will add a logging system to solve the problem that
one actually need to recompile rdesktop from source to enable
different debug logging.
- Same logging api for all kind of logging and messages to
end user.
- Adding -v for verbose output when running rdesktop.
- All messages are logged into a subject and with a type, eg:
logger(Keyboard, Notice, "Autos-electing %s based on locale.", locale);
- Debug logging is enabled trough a environment variable RDEKSTOP_DEBUG,
which specifies subjects of interest, comma separated. There is a special
subject named All which includes all subject for debug loggin. There is also
a simple logic opeartor '!' = NOT which can be used in combination like:
RDESKTOP_DEBUG=All,!Graphics,!Sound
Which would give debug log output for All subject except Graphics and Sound.
to streams in CredSSP. (The other part of bug #383.

- Add implementation of TSSmartCardCreds and TSCSPDataDetail for
CredSSP protocol.
- Add handling of long opts for getopt()
- Added 4 new long opts for providing information to CredSSP which
is required for smartcard credentials.
- Updated manual with information about the new arguments.
If smartcard authentication is request by commandline "-i" option,
and no CredSSP smartcard options is provided, rdesktop will
negotiate to use SSL and warn.
