/**
@file
This service provides functions that allow plugins to support
the KILL statement.
In MySQL support for the KILL statement is cooperative. The KILL
statement only sets a "killed" flag. This function returns the value
of that flag. A thread should check it often, especially inside
time-consuming loops, and gracefully abort the operation if it is
non-zero.
thd_is_killed(thd)
@return 0 - no KILL statement was issued, continue normally
@return 1 - there was a KILL statement, abort the execution.
thd_kill_level(thd)
@return thd_kill_levels_enum values
