Also some cleanups, the most important are:
- meaningful ctor on Jrd::Lock, helping to avoid code dup
- avoid unneeded h-file dependencies, making boot build engine dependent
or as dynamic library, depending upon platform requirements). Self-registering plugins
need not export any functions, instead they call fb_register_plugin() on startup.
Reworked all user management to use self-registering plugins.
Removed system table RDB$USERS. PLG$USERS is not created automatically by plugin, but
will be later (work in progress).
2. Introduce new private API calls, fb__shutdown() and fb__shutdown_callback().
3. Introduce fb_smp_server - binary to run superclassic on posix.
4. Various cleanups.
service_thread_CS):
1)Moving object files of utils to superclient temp directory
2)Add new define STD_UTIL
3) Hide utils functions to local scope of libfbembed
Build tested Solaris x86 and Linux x86
ThreadData.cpp - thread control class to use in Client
thd.cpp - thread control class to use in Server
To avoid making global visibility of a lot of THD_* ISC_event and so functions in libfbclient.so
(Can be breakable but needed)
