Move tar detection and compression logic to common.
Consolidate tar archive identification and compression-type detection
logic into a shared location. Currently used by pg_basebackup and
pg_verifybackup, this functionality is also required for upcoming
pg_waldump enhancements.
This change promotes code reuse and simplifies maintenance across
frontend tools.
