4d3d90ad0a Slight tweak to previous commit: don't forget to call _http_seterr() if
we get a genuine 416 reply.

b5e1214546 When restarting a transfer that has already completed, the server will
reply with a 416 error code (requested range not satisfiable) because
we ask it to start at the end of the file.  Handle this gracefully by
considering a 416 reply a success if the requested offset exactly
matches the length of the file and the requested length is zero.

dea29ca1d5 First step towards SSL support: wrap connections in a 'struct connection'
which contains the socket descriptor, the input buffer and (yet unused)
SSL state variables.  This has the neat side effect of greatly improving
reentrance (though we're not *quite* there yet) and opening the door to
HTTP connection caching.

This commit is inspired by email conversations with and patches from
Henry Whincup <henry@techiebod.com> last fall.

4cd0119367 Do not use __progname directly (except in [gs]etprogname(3)).
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

e19e6098b3 Reindent, and add parentheses to return statements. Some functions in
ftp.c and http.c now have exceedingly long lines due to deep nesting;
this will be corrected by reorganizing the code in a later revision.

c78f1cc912 Ignore environment variables that are set but empty.
Sort out the size / length confusion.  Always try to report the *real* file
size in the url_stat structure, no matter how much of it is actually being
sent, and try to detect inconsistencies between sizes.

Rearrange the request loop to avoid having to add meaningless code just to
silence compiler warnings.

Switch to a more sensible and consistent interface for the _http_parse*()
functions.

87b41116cc Don't try to skip to the requested offset if the server returns more data
than requested.  Instead, inform the caller of the real offset by modifying
the offset field in the original struct url, and let him decide how to handle
the situation.

1a5faa1061 Introduce fetchXGet*(), which combine the functionalities of fetchGet*() and
fetchStat*().  In most cases, either fetchGet*() or fetchXGet*() is a wrapper
around the other; in all cases, calling fetchGet*() is identical to calling
fetchXGet*() with the second argument set to NULL.

c789727701 Don't forget to set file descriptor to -1 after closing it, since the code
outside the loop inspects it to determine whether or not we succeeded in
retrieving the requested document. This fixes a bug where fetchGetHTTP()
would return a FILE with an invalid file descriptor if it hit the redirect
limit without locating the requested document.

e4878e39a3 Extensive rewrite of the HTTP code. The new code is significantly cleaner and
more robust, and somewhat more efficient. It also handles authorization and
redirects properly, and supports timeouts like the FTP code.

and in other parts of libfetch.
