Made the public headers checksrc compliant
Removed types.h (it's been unused since April 2004)
Made the root makefile do make in include by default as well, so that
TAGS and the checksrc will work better.
the names of the curl_off_t formatting string directives now become
CURL_FORMAT_CURL_OFF_T and CURL_FORMAT_CURL_OFF_TU.
CURL_FMT_OFF_T -> CURL_FORMAT_CURL_OFF_T
CURL_FMT_OFF_TU -> CURL_FORMAT_CURL_OFF_TU
Remove the use of an internal name for the curl_off_t formatting string directives
and use the common one available from the inside and outside of the library.
FORMAT_OFF_T -> CURL_FORMAT_CURL_OFF_T
FORMAT_OFF_TU -> CURL_FORMAT_CURL_OFF_TU
