Rename thread_init() function to thread_init_dirmngr() to avoid conflict on AIX

[Lakshmi-Surekha]

Hi All,

When building GnuPG on AIX, the build fails in the dirmngr component due to a naming conflict with the system-provided thread_init() function.

AIX has thread_init() declaration in /usr/include/sys/thread.h, which conflicts with the function defined in dirmngr.c.

Affected Files

This naming conflict exists in:

dirmngr/dirmngr.c

Proposed Fix

Rename the function to something unambiguous, e.g.:

thread_init_dirmngr
