http: Allow multiple non-file Content-Disposition

Now, slweb accepts requests such as:

--boundary
Content-Disposition: form-data; name="field1"

value1
--boundary
Content-Disposition: form-data; name="field2"

value2
--boundary
Content-Disposition: form-data; name="field3"; filename="example.txt"

The following breaking changes have been introduced:

Member "dir" from struct http_post was a leftover from the days where
slcl and slweb were one project. It did not make sense for slweb, since
it should not decide which Content-Disposition names are allowed. In
other words, "dir" was only relevant in the scope of slcl.

Member "n" from struct http_post used to have two meanings:

- The length of a URL-encoded request.
- The number of files on a multipart/form-data request.

Since "npairs" had to be introduced to struct http_post, it did not make
sense to keep this dual meaning any more. Therefore, "n" has been
restricted to the former, whereas a new member, called "nfiles", has
been introduced for the latter.
