Description
After hook glibc, there are some clear memory leak in modsecurity transaction.
There are pcre_malloc and pcre_free in this module, so I hook all memory callback in msc_transaction, and finally resolve the memory leak in modsecurity transaction.
(I have implemented, however, I won't add a PR without discussion.)

Research direction
Start by reviewing the existing memory-callback implementation described in the issue, focusing on pcre_malloc, pcre_free, and msc_transaction. Verify the proposed hook against the transaction lifecycle and use a focused memory-leak check; done means the transaction no longer leaks memory without regressions.
