This commit adds a new argument to smp_fetch_url_param
that makes the parameter key comparison case-insensitive.
Several levels of callers were modified to pass this info.
Extract function h2_parse_cont_len_header() in the generic HTTP module.
This allows to reuse it for all HTTP/x parsers. The function is now
available as http_parse_cont_len_header().
Most notably, this will be reused in the next bugfix for the H3 parser.
This is necessary to check that content-length header match the length
of DATA frames.
Thus, it must be backported to 2.6.
http_is_default_port() can be used to test if a port is a default HTTP/HTTPS
port. A scheme may be specified. In this case, it is used to detect defaults
ports, 80 for "http://" and 443 for "https://". Otherwise, with no scheme, both
are considered as default ports.
http_get_host_port() function can be used to get the port part of a host. It
will be used to get the port of an uri authority or a host header
value. This function only look for a port starting from the end of the
host. It is the caller responsibility to call it with a valid host value. An
indirect string is returned.
While http_parse_scheme() extracts a scheme from a URI by extracting
exactly the valid characters and stopping on delimiters, this new
function performs the same on a fixed-size string.
Replace http_get_path by the http_uri_parser API. The new functions is
renamed http_parse_path. Replace duplicated code for scheme and
authority parsing by invocations to http_parse_scheme/authority.
If no scheme is found for an URI detected as an absolute-uri/authority,
consider it to be an authority format : no path will be found. For an
absolute-uri or absolute-path, use the remaining of the string as the
path. A new http_uri_parser state is declared to mark the path parsing
as done.
Replace http_get_authority by the http_uri_parser API.
The new function is renamed http_parse_authority. Replace duplicated
scheme parsing code by http_parse_scheme invocation. A new
http_uri_parser state is declared to mark the authority parsing as done.
Replace http_get_scheme by the http_uri_parser API. The new function is
renamed http_parse_scheme. A new http_uri_parser state is declared to
mark the scheme parsing as completed.
Implement a http uri parser type. This type will be used as a context to
parse the various elements of an uri.
The goal of this serie of patches is to factorize duplicated code
between the http_get_scheme/authority/path functions. A simple parsing
API is designed to be able to extract once each element of an HTTP URI
in order. The functions will be renamed in the following patches to
reflect the API change with the prefix http_parse_*.
For the parser API, the http_uri_parser type must first be
initialized before usage. It will register the URI to parse and detect
its format according to the rfc 7230.
Add a function that compares two etags that might be of different types.
If any of them is weak, the 'W/' prefix is discarded and a strict string
comparison is performed.

Directly including stddef.h in many files results in it being processed
multiple times while it can be centralized in api-t.h and be guarded
against multiple inclusions. Doing so reduces the number of preprocessed
lines by 1200!
So the enums and structs were placed into http-t.h and the functions
into http.h. This revealed that several files were dependeng on http.h
but not including it, as it was silently inherited via other files.
