global: Fix spelling mistakes in comments Original work by @andreasschulze and @jsoref

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

global: Fixed mismatched bool vs. int/pointer handling I don't think these fix any actual bugs.

lib: Fixed read buffer overflow in wildcard_match*() Patch by Hanno Böck. Note that input to wildard_match*() is always coming only from trusted sources, like config file or doveadm commands.

lib: wildcard_match() should have matched "*" wildcard against an empty "" string also. This fixes global ACL "*" matching the root namespace when creating new mailboxes.

lib: wildcard-match - use NULL not 0 for pointers Flagged by sparse.

Added wildcard_match*() for matching strings with '*' and '?' wildcards. --HG-- branch : HEAD
