[fedfs-utils] 0.7-stable: 9 c-sets rebased from master

[Jim Meyering]

[PATCH 1/9] mount: avoid two-byte heap write overrun
[PATCH 2/9] fedfsd: don't return freed memory through **pathname
[PATCH 3/9] build: avoid automake warnings about AM_PROG_AR
[PATCH 4/9] mount: don't make -s (sloppy) imply -v (verbose)
[PATCH 5/9] mount: don't leak upon LDAP parse failure
[PATCH 6/9] nsdb: don't leak a read buffer upon certfile open
[PATCH 7/9] libsi: don't leak a struct srvinfo upon failed strdup
[PATCH 8/9] fedfsd: don't double-free upon ENOMEM
[PATCH 9/9] libnsdb: do not read beyond end of malloc'd buffer; do

These are the same 9 changes that I posted for master.
Each was cherry-picked trivially to the 0.7-stable branch.
