struct http_response did not provide users any void * that could be used
to maintain a state between calls to an asynchronous HTTP response.
On the other hand, the user pointer could not be used for this purpose,
since it is shared among all HTTP clients for a given struct handler
instance.
Moreover, the length callback was still not supporting this feature,
which in fact might be required by some users. Implementing this was
particularly challenging, as this broke the current assumption that
all bytes on a call to http_read were being processed.
Now, since a client request can only be partially processed because of
the length callback, http_read must take this into account so that the
remaining bytes are still available for future calls, before reading
again from the file descriptor.

Sometimes, library users cannot return a HTTP response as soon as the
request is received, or the operations that are required to generate it
can take a long time.
In order to solve this, libweb adds a new member to struct
http_response, namely step, which must be assigned to a function
whenever a HTTP response should be generated in a non-blocking manner.
Leaving the function pointer as null will fall back to the default
behaviour.

A malicious user could inject an infinite number of empty files or
key/value pairs into a request in order to exhaust the device's
resources.

Even if libweb already parses some common headers, such as
Content-Length, some users might find it interesting to inspect which
headers were received from a request.
Since HTTP/1.1 does not define a limit on the number of maximum headers
a client can send, for security reasons a maximum value must be provided
by the user. Any extra headers shall be then discarded by libweb.
An example application showing this new feature is also provided.

It was found out there was another project of the same name around
(https://git.sr.ht/~strahinja/slweb/), also related to website
generation.
In order to avoid confusion, a new name has been chosen for this
project. Surprisingly, libweb was not in use by any distributions
(according to https://repology.org and AUR index), and it should
reflect well the intention behind this project i.e., being a library
to build web-related stuff.
