	* plugins/symbol-db/tables.sql:
	performance improvements. On average tests with benchmark test program
	I could reach 11.9 ms/symbol, which is quite fine (my pc is an old P4 1.8GHz). 
	Slightly modified tables.sql, which require a full re-scan of the projects:
	even when populating now the gui seems responsive and not blocking at all.
	Fixed #565769 – symbol-db blocks anjuta when files are removed. Now performance
	for removing files is at the top.

	* plugins/symbol-db/test/benchmark.c (on_scan_end):
	* plugins/symbol-db/test/main.c (main):
	fixed some compiling issues.
