First we need to remove the tevent_fd structures without
tevent_fd_set_auto_close(). Closing the fd needs to be the last
thing...

This changes the mapping of internal log levels to syslog priorities to
match the previously defined helper macros. The idea is that this better
maps to the actual use of log levels in the Samba code.
unchanged
log level | priority
0 | ERROR
1 | WARNING
2 | NOTICE
before
log level | priority
3 | INFO
4 and higher | DEBUG
after

Using Context.add_timer resulted in crashes due to missing type object
and bad reference handling.
Add a TeventTimer_Type struct, and introduce a clear ownership/lifetime model.
Add a "add_timer_offset" to allow adding timers from Python. (add_timer
requires passing struct timeval as a Python integer, which can't really
be done portably).

Samba provides its own set of SHA function, which would replace
libc-provided flavors. This is a problem because while the prototypes
are the same, the context structure are different. As a result,
when connecting to a LDAP/SSL directory, we go through
libldap/libssl/libcrypto and there libcrypto expects to call libc
SHA functions, not Samba's.
The fix is to check for SHA function presence and rename Samba's
version to avoid a clash.
