acl: Don't deref a potentially uninitialized pointer in acl_global_file_read

acl: Fix checking create (k) permission in global acl-file Just because the global ACL file hasn't changed since it was last refreshed for another ACL object, it doesn't mean that those ACLs don't need to be applied to this ACL object. This didn't usually cause problems, because the initial ACL object refresh was always done due to local-path refresh returning "needs a refresh". The only exception was when acl_object_init_from_parent() was called, because it added an empty non-NULL validity for the local-path, so the "needs a refresh" wasn't returned. This happened only when trying to CREATE or RENAME mailbox under a parent where user didn't have create permissions. This affected only when using a single global acl-file, not when using global acl directory containing per-mailbox files.

acl: Fix checking whether global acl-file has changed We always assumed that it was changed and re-read it.

acl: Global ACL file was parsed as if it was local ACL file This caused some of the ACL handling not work exactly as expected.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

acl: Global ACLs now support "patterns with spaces inside quotes"

acl: Global ACL file used only the first matching rights line, not merging all the matches.

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..
