cf54474e38 NetServices: Implement BHttpTime, parse_http_time() and format_http_time().
These utilities convert timestamp strings that are formatted according to
the HTTP RFC into BDateTime objects, and vice versa.

13bfff7be3 NetServices: Implement BHttpStatusCode, BHttpStatusClass and Redirects
The user of the API can set whether redirects should be followed, and if so,
how many. This is part of the BHttpRequest API. The BHttpSession then follows
those instructions, and executes the maximum number of redirects the user
would like to follow.

As part of this commit, the BHttpStatusClass and BHttpStatusCodes helper enums
have been added, to give a friendlier access to HTTP status codes and status
classes.

59c359e5a9 NetServices: implement support for HEAD requests and 204 responses.
These particular responses will not have a body. This is now handled by the
BHttpSession object. There is also a minor fix in here that prevents a crash
when multiple requests are handled by the DataThread at the same time, and not
all of the requests have events.

d482381d2c NetServices: partial implementation of the receive function
This initial implementation contains a lot of extra debuggin output that will
be removed in future changes. It is now possible to run a simple GET request
to the test server with gzip encoding.

8ccf8fb44d NetServices: Rewrite BHttpFields to use raw strings as underlying data storage
This change also drops the principle that fields with the same keys would be
grouped together. This was initially inspired by Boost::Beast, but it means a
lot of extra copying of data when adding/organizing the list, as well as
inefficient querying on each add. Now that the design choice is to fully go
for the raw string as underlying data storage, that choice is not necessary.
In the future it may be able to emulate the grouping or retrieving of lists
of values in the API, rather than as a fundamental principle of the data
storage.

3b172a3dc6 NetServices: implement hostname resolution and connection for BHttpRequest
BHttpSession::Execute() moves the request into the session, and returns a future BHttpResponse
object. Currently implemented are resolving the hostname, and opening the connection.

There is some scaffolding for the actual data transfer.

3b2aa6c31b NetServices: Add the BNetworkRequestError type
This is a generic error type that can be used by multiple protocols to describe errors that can
occur while processing a request. The error type supports adding an additional error code in cases
where there is an underlying system error.

The type will be used to describe errors that occur while processing requests by BHttpSession, and
it is generally going to be thrown by the receiving BHttpResult.

6ce6e96470 NetServices: Introduce BHttpRequest class
Objects of this class describe a HTTP request. It contains several convenience
functions that will allow a user to describe the properties of the request.
More options to be added later.

ec865cb87e NetServices: Add BHttpMethod that represents a HTTP method
This class provides defaults and performs basic validation for HTTP Methods as
defined by the standard. They will be used in conjunction with a future
BHttpRequest class.

a8003a7030 NetServices: Introduce BHttpFields to query and manipulate fields in HTTP messages
HTTP messages (requests and responses) have a header section that can contain
HTTP headers. These headers consist of name, value pairs. This class can be
used to query the headers on a response, and build a list of headers for a
request.

The internal implementation is designed around two different methods of storing
the underlying data. For HTTP requests, the name, value pairs are stored as
owned BString objects. For responses, the assumption is that there is a byte
buffer that contains the data and that has the same lifetime as the BHttpFields
object. The name, value pairs will then be stored as std::string_view to the
underlying buffer.

Still to do is:
 - The method to convert a BHttpFields list into a string buffer to transmit.
 - The method to parse a string buffer and turn it into a BHttpFields object.
