Handle tcache init failures gracefully

Browse Source 
tsd_tcache_data_init() returns true on failure but its callers ignore
this return value, leaving the per-thread tcache in an uninitialized
state after a failure.

This change disables the tcache on an initialization failure and logs
an error message.  If opt_abort is true, it will also abort.

New unit tests have been added to test tcache initialization failures.
