re-committed for archival purposes.

new static archive_inited variable, so that archive_db_end() will do something only if archive_db_init() was run before
(protection against destroying uninited mutex in the case where mysqld fails early at startup (before archive_db_init() was called)
and then calls archive_db_end() to clean up).

Set of fixes requested by Kent in IRC. Tested (except the windows changes since I am trusting Kent...). No windows compiles here folks...

binlog-do-db or binlog-ignore-db are in effect.   (In the future 5.1? 5.0? I think 
each statement should be verified against the filtering criteria based on the database
it *uses* and not the *current* one.  But, right now the *current* database is what 
counts according to the semantics of the manual.)

It was a thread stack overrun.
IA64 had its own stack size section already.
Enlarged its default stack size from 192K to 256K.

reset mysql->net.last_error": the solution is to clear
MYSQL->net error before performing COM_CLOSE: if the call
succeeds, the connection is usable for other statements.
More comprehensive fix is to clear MYSQL->net for all
recoverable errors at the time they happen, it will be
implemented in 5.0 as it introduces incompatibility in behavior.

it also works on file names with special characters.
