Fixed some sign comparison warnings.
Added utility functions to fr::Packet's for:
Getting read cursor position.
Relative read cursor seeking.
Asserting that data remains in the packet
Getting the amount of data remaining
Getting the size of the packet
Fixed TcpSocket::set_descriptor(nullptr) causing an invalid read from address 0x0.
Improved HTTP response/request parsing so that they report a parse failure if the first few bytes of the HTTP request don't match the expected format rather than continuing to look for an end of header.
Fixed broken fr::Http::url_encode() implementation.
Optimised fr::Http::url_decode() implementation.
Added fr::Http unit tests.
Socket mutexes are no longer really required, and so have been removed.
Added more tests for network encoding functions, and the URL parser.
The URL parser now returns a path preceeded with a '/' instead of cutting it out. Added get_uri() to URL, for getting the whole URI, so users don't have to concat it themselves from the more specialised functions.
Fixed default socket connect timeout checking for the wrong value.
Fixed request_type_strings not containing all of the possible request types.
Fixed README using old socket close syntax.
Cleaned up the examples a bit.
Receiving an http request/response will now return errors like HttpHeaderTooBig, instead of the type being set to that.
Added fr::Socket::status_to_string for converting status values into English strings.
Added the ability to disable certificate verification for SSL sockets which is useful for testing.
Added the ability to specify maximum HTTP request header/body sizes in the CMake build config to prevent a malicious client from causing OOM errors.
Fixed a bug in HttpResponse and HttpRequest parse causing it to abort if the request is invalid in some cases.
fr::HttpSocket has been removed.
fr::Sendable has been added. Classes can inherit this if they want to be sendable through sockets. Both fr::Http (which is inherited by fr::HttpRequest and fr::HttpResponse), and fr::Packet inherit this, to allow them to be sent through fr::Socket::send()/fr::Socket::receive().
Fixed broken fr::SocketSelector and fr::SocketReactor, as they no longer accepted fr::Listener's due to fr::Listener no longer inheriting fr::Socket.
Fixed Content-Length header being added to Http responses even if there's a pre-existing one.
Fixed header parsing sometimes adding a carriage return to the header value.
Removed useless copy/move constructors from HttpResponse, causing issues.
fr::TcpSocket checked if the recv response was greater than 0, which created issues as 0 is a valid result if no data was received and no error occurred.
fr::HttpResponse::construct() now adds in a content-length header.
fr::HttpResponse::parse trims the body if it's larger than content length.
fr::Http::set_uri() now prepends a '/' if one's not provided.
Fixed fr::Http::parse_header from cutting off the end of headers.
Build errors have been fixed, but there are build warnings remaining about unsafe conversions, because Visual C++'s network conversion functions have a differing return type to mine. To be fixed in the future.
