imap: Implemented support for the LITERAL- capability. This replaces the LITERAL+ capability when the imap_literal_minus setting is enabled.

lib-imap: imap-parser: Turned the fatal error flag into a proper error code.

lib-imap: imap-parser: Made the fatal result parameter of imap_parser_get_error() optional.

lib-imap: Added IMAP_PARSE_FLAG_STOP_AT_LIST for stopping after '('

lib-imap: Added IMAP_PARSE_FLAG_SERVER_TEXT that fixes parsing input from IMAP server.

Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786

imap parser: Added support for parsing literal8 (for BINARY extension)

imap-parser: Added IMAP_PARSE_FLAG_INSIDE_LIST flag. Adds mode flag to IMAP parser which makes it assume it is inside a (...) list, making ')' equal to EOL and '\n' an error.

lib-imap: Added reference counting to imap parser.

lib-imap: Changed imap_arg accessing APIs. The new one is easier for both coders and static analyzers. --HG-- branch : HEAD

lib-imap: Added imap_parser_set_streams(). --HG-- branch : HEAD

Inlined IMAP_ARG_*() macros' error handling functions. --HG-- branch : HEAD

imap-parser: Added IMAP_PARSE_FLAG_MULTILINE_STR flag. --HG-- branch : HEAD

Added IMAP_PARSE_FLAG_ATOM_ALLCHARS. --HG-- branch : HEAD

Added imap_parser_get_literal_size() and imap_parser_read_last_literal() to help continue parsing input after IMAP_ARG_LITERAL_SIZE when IMAP_PARSE_FLAG_LITERAL_SIZE is used. --HG-- branch : HEAD

Removed _ prefix from all public APIs. --HG-- branch : HEAD

Renamed __attr_*__ to ATTR_*. Renamed __attrs_used__ to ATTRS_DEFINED. --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Renamed IS_ATOM_SPECIAL() to IS_ATOM_SPECIAL_INPUT() and added a new IS_ATOM_SPECIAL() that contains all of the specials. --HG-- branch : HEAD

Added IMAP_ARG_TYPE_IS_STRING() --HG-- branch : HEAD

Changed imap-parser API to use standard arrays for lists instead of its own imap_arg_list struct. --HG-- branch : HEAD

Added more consts to imap-parser API --HG-- branch : HEAD

Added some noreturn attributes and fixed warnings caused by them. --HG-- branch : HEAD

deinit, unref, destroy, close, free, etc. functions now take a pointer to their data pointer, and set it to NULL. This makes double-frees less likely to cause security holes. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Compiler warning fixes --HG-- branch : HEAD

s/occured/occurred/ --HG-- branch : HEAD

And removed the other added atom-specials as well.. --HG-- branch : HEAD

Removed ']' from atom-specials because our FETCH BODY[] handling fails then.. --HG-- branch : HEAD

Updated IS_ATOM_SPECIAL() list and moved it to header file. --HG-- branch : HEAD

Fixes for parsing BODYSTRUCTURE --HG-- branch : HEAD

IMAP parser memory limits are now enforced by bytes per line rather than limiting maximum amount of tokens per line. Default is 64k now, which should help with the huge message sets generated by some clients. --HG-- branch : HEAD

Don't do x-unknown mime encoding. Correct way is to just send them as literals to client. ENVELOPE, BODY and BODYSTRUCTURE replies are now always sent as literals if they contain 8bit text, '"' or '\' characters. Added option to IMAP parser to return literals with IMAP_ARG_LITERAL type. --HG-- branch : HEAD

Disconnect client if given non-sync literal size is too large. Better than eating the input. --HG-- branch : HEAD

Support for LITERAL+ extension. --HG-- branch : HEAD

comment fix --HG-- branch : HEAD

Naming style changes, finally got tired of most of the typedefs. Also the previous enum -> macro change reverted so that we don't use the highest bit anymore, that's incompatible with old indexes so they will be rebuilt. --HG-- branch : HEAD

Actually, don't allow NIL with IMAP_ARG_LIST(). --HG-- branch : HEAD

Don't access ImapArg's union members directly - too easy to mess up. Fixes a crash with feeding non-string parameters to SEARCH/SORT commands. --HG-- branch : HEAD

Limited max. command argument elements to 128. Added more verbose error messages to IMAP parser. --HG-- branch : HEAD

Renamed IBuffer and OBuffer to IStream and OStream which describes their functionality better. I tried to keep the variable names and comments also sensible. --HG-- branch : HEAD

ImapArgList changed from linked list to array. easier to handle that way. --HG-- branch : HEAD

Split IOBuffer into mmaped IBuffer, file IBuffer, memory data IBuffer and file OBuffer. --HG-- branch : HEAD

Introduced uoff_t which is the unsigned-equilevant of off_t. This was needed to be able to handle off_t overflows properly. Also changed a few unsigned int fields into uoff_t so we should now support >2G mails if uoff_t is 64bit. Also fixed several potential integer overflows. --HG-- branch : HEAD

Initial revision --HG-- branch : HEAD
