Subject: [PATCH] Fix bug #63595 GMP memory management conflicts with other

 libraries using GMP

Drop use of php memory allocators as this raise various conflicts

with other extensions and libraries which use libgmp.

No other solution found.

We cannot for ensure correct use of allocator with shared lib.

Some memory can allocated before php init

Some memory can be freed after php shutdown

Known broken run cases

- php + curl + gnutls + gmp

- mod_gnutls + mod_php + gnutls + gmp

- php + freetds + gnutls + gmp

- php + odbc + freetds + gnutls + gmp

- php + php-mapi (zarafa) + gnutls + gmp
