When working on the documentation, I discovered GIT_TRACE_PACK_ACCESS, which uses a completely separate trace implementation that is 3 times faster by keeping the file open...so this round includes a performance patch that brings the trace API up to speed. Changes since v6: [04-06]: New. [07-08]: Separated the 'disable for test' aspect into a separate patch. GIT_TRACE_BARE=1 is set in test-lib.sh rather than individual tests. Moved static trace_bare variable from global scope into prepare_trace_line(). [09]: Cast timeval.tv_usec to long to prevent compiler warning. [11,13]: Factor out '#define TRACE_CONTEXT __FILE__' so that it can be easily changed to __FUNCTION__. [14]: Added GIT_TRACE_PERFORMANCE to Documentation/git.txt [15-16]: New. [01-03,10,12] are unchanged save resolving conflicts.
