[Pgpool-committers] pgpool - pgpool-II: Allow to use regular expressions in black and white

[User T-ishii]

Log Message:
-----------
Allow to use regular expressions in black and white function list.
Patch created by Gilles Darold. Here is the description he wrote.

Regex patch :

    The regex struct array is stored in pool_config struct, it is
    dynamically expendable by PATTERN_ARR_SIZE when it reached
    NxPATTERN_ARR_SIZE (start with 16 regex max).

    All entries in white_function_list or black_function_list are stored
    in this array with a flag to differentiate them. To preserve
    backward compatibility and prevent partial matching lists entries
    are all prefixed with '^' and ended with '$' if not already done.
    This also mean that if we want to match function beginning with
    "write_" it has to be written : "write_.*". Indeed "^write_.*$"
    works too.
