lib-mail: Added message_header_line_write()

Removed CONTEXT_TYPE_SAFETY macro and reimplemented its functionality better. gcc/clang now gives a compiler error in many places if callback isn't exactly what was expected. It's also now much easier to add more of these checks.

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

message-header-parser: MESSAGE_HEADER_PARSER_FLAG_CLEAN_ONELINE should affect only full_line. Otherwise it behaves inconsistently between hdr->use_full_value=TRUE/FALSE. --HG-- branch : HEAD

Added more consts, ATTR_CONSTs and ATTR_PUREs. --HG-- branch : HEAD

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

Header parser has now flags parameter to tell it how to handle linefeeds. Changed message parser's boolean parameter to enum as well. --HG-- branch : HEAD

Type safe callbacks weren't as easy as I thought. Only callback(void *context) can be handled generically. Others can be handled specially, but only if all the parameters are pointers, otherwise eg. int parameter can be replaced with long without compiler giving any warnings. --HG-- branch : HEAD

Added context parameter type safety checks for most callback APIs. --HG-- branch : HEAD

Added crlf_newline flag to header parser, which is set if the header ended with CR+LF instead of LF. --HG-- branch : HEAD

Rewrote the message bodystructure parser to allow parsing from non-blocking streams. Also did a couple of API changes and cleanups. --HG-- branch : HEAD
