  Add an embryo of a TLS-aware error handling system This adds the per-thread global variable git_errno to the system, which callers can examine to get information about an error. Two helper functions are added to reduce LoC-count for the library code itself. Also, some exceptions are made for running sparse on GIT_TLS definitions, since it doesn't grok thread-local variables at all. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.
