acl-plugin: Make iterators more conforming The *_next functions return true/false, deinit will report errors and end result.

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

acl plugin: Added an alternative global ACL file that can contain mailbox patterns. Instead of pointing the global ACL path to a directory use a file instead. The file format is "<mailbox pattern> <normal ACL line>". Most importantly this can be used to specify default ACLs for namespaces. The mailbox pattern uses "*" and "?" wildcards currently. I'm not sure if I should still change them to IMAP "*" and "%" wildcards. That would make the behavior more complex ("%" depends on hierarchy separator), slightly slower and quota code is already also using the */? wildcards..

acl: Code cleanup by moving around the code and renaming functions.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]
