[PATCH] Fix xgettext warnings and incomplete format strings due to macros

Hi,

Scanning the translations template file fails due to APR_UINT64_T_FMT
being used as is in format strings. This is from r1575628 (fsfs l2p
index), also from log-addressing branch, and r1595579 (sync of same to
FSX). While this works at execution time (modulo actually translating),
xgettext cannot handle that:

> make locale-gnu-pot
> Building subversion.pot...
> ../libsvn_fs_fs/index.c:597: warning: Although being used in a format string position, the msgid is not a valid C format string. Reason: The string ends in the middle of a directive.
> ../libsvn_fs_fs/index.c:657: warning: Although being used in a format string position, the msgid is not a valid C format string. Reason: The string ends in the middle of a directive.
> ../libsvn_fs_fs/cached_data.c:944: warning: Although being used in a format string position, the msgid is not a valid C format string. Reason: The string ends in the middle of a directive.
etc.

Please review the attached patch. It basically wraps the
APR_UINT64_T_FMT into a call to apr_psprintf. The introduction of a pool
parameter to some private functions seems necessary.
