/*
The thread pool requires access to some MySQL server error codes, this is
accessed from mysqld_error.h.
We need access to the struct that defines the thread pool plugin interface
which is accessed through scheduler.h.
All accesses to THD variables and functions are defined in this header file.
A thread pool can also use DEBUG_SYNC and must thus include
debug_sync.h
To handle definitions of Information Schema plugins it is also required
to include sql_profile.h and table.h.
