Use TLS variables instead of pthread specific interface

Registered by Alexey Kopytov

We should make use of the TLS mechanism provided by some compilers and platforms (notably GCC on Linux) instead of the slow pthread specific interface.

Current users of thread-local variables:
- current_thd
- my_errno
- sql_alloc
- performance schema
- threadpool
