Pull request overview

This PR adds new ModSecurity C API entry points to let connectors query which rules matched during a transaction, intended to support downstream integration needs (referenced by the ModSecurity-nginx PR).

Changes:

• Add msc_get_matched_rules_count(Transaction*) to return the number of stored rule match/message records on a transaction.
• Add msc_get_matched_rule_id(Transaction*, size_t index) to fetch the rule ID for the N-th stored record.
• Update public header to expose the new APIs and include <stdint.h> for int64_t.

Regarding the two remaining issues in SonarCloud: all the other extern "C" functions are inside the namespace, and I don't want to write these two differently.
