Merging r4009, r4133, r4184, r4201, r4202, r4203, r4204, r4205: Miscellaneous fixes: *) Fix of names of the referer hash size directives introduced in r3940. *) Cosmetics: replaced NGX_CONF_TAKE1 to NGX_CONF_FLAG for "sendfile" and "chunked_transfer_encoding" directives, to be in line with all directives taking a boolean argument. Both flags will ensure that a directive takes one argument. *) Improved ngx_parse_time() code readability. *) Preallocating exact number of default MIME types entries. *) Stylistic change in checking the boolean expression. *) Replaced magic constants representing default values of some directives with appropriate #define's. *) Fixed grammar in a comment. *) Fixed two minor bugs in "types" parsing code.
