3ef2e05c4d lxc_container.c: avoid a leak on error paths 
* src/lxc_container.c (lxcContainerMountBasicFS): Don't leak upon failure.
Add "cleanup:" label and change each post-allocation failure to
use "goto cleanup" rather than returning immediately.

 src/lxc_container.c: if (oldroot) VIR_FREE(oldroot)
 src/lxc_container.c: if (newroot) VIR_FREE(newroot)
 Makefile.maint: found useless "if" before "free" above

and:

 src/lxc_container.c:317:
 Makefile.maint: found trailing blank(s)

fd52c6ff67 avoid many format string warnings 
Building with --disable-nls exposed many new warnings like these:
virsh.c:4952: warning: format not a string literal and no format ...
util.c:163: warning: format not a string literal and no format arguments
All but one of the following changes add a "%s" argument before
the offending _(...) argument.

This was the only manual change:
* src/lxc_driver.c (lxcVersion): Use %s and strerror(errno)
rather than %m, to avoid a warning from gcc -Wformat-security.

Add "%s" before each warned about format-string-with-no-%-directive:
