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.
