Lockdep is initialized at compile time now.  Get rid of lockdep_init().

2b62c2dbb9 tools/liblockdep: explicitly declare lockdep API we call from liblockdep 
It seems that newer gcc complains about lack of explicit declaration for some
of the API we use, add it in.

b10827814e tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire 
Commit fb9edbe984 shortened held_lock->check from a 2-bit field
to a 1-bit field.

Make liblockdep compatible with the new definition by passing check=1
to lock_acquire() calls, rather than the old value check=2 (which
inadvertently disabled checks by overflowing to 0).

Without this fix, several of the test cases in liblockdep run_tests.sh
were failing.

5a52c9b480 liblockdep: Add public headers for pthread_rwlock_t implementation 
Both pthreads and lockdep support dealing with rwlocks, so
here's the liblockdep implementation for those.

45e6207464 liblockdep: Add public headers for pthread_mutex_t implementation 
These headers provide the same API as their pthread mutex
counterparts.

The design here is to allow to easily switch to liblockdep lock
validation just by adding a "liblockdep_" to pthread_mutex_*()
calls, which means that it's easy to integrate liblockdep into
existing codebases.
