[ftpc] Add a config option to specify a data connect timeout. That is how long the ftp client will wait for the server to connect to the data socket. If this timeout occurs, an error will be returned to the caller and the ftp client process will be terminated.

Own Id: OTP-9545

[httpc] Wrong Host header in IPv6 HTTP requests. When a URI with a IPv6 host is parsed, the brackets that encapsulates the address part is removed. This value is then supplied as the host header. This can cause problems with some servers. A workaround for this is to use headers_as_is and provide the host header with the requst call. To solve this a new option has been added, ipv6_host_with_brackets. This option specifies if the host value of the host header shall include the brackets or not. By default, it does not (as before).

[httpc] httpc manager crashes. When a request results in a retry, the request id will be "reused" in the previous implementation a race condition could occur causing the manager to crash.

[httpc] Issuing a request (httpc:request) to an host with the ssl option {ip, {127,0,0,1}} results in an handler crash. The reason was that the connect call resulted in an exit with reason badarg (this was the same for both ssl and gen_tcp).

[httpc] If a request times out (not connect timeout), the handler process exited (normal) but neglected to inform the manager process. For this reason, the manager did not clean up the request table., resulting in a memory leak. Also the manager did not create a monitor for the handler, so in an unforseen handler crash, this could also create a memory leak.

The erl_script_timeout config option is ducumented as a number of seconds. But when parsing the config, in the new format (not a config file), it was handled as if in number of milliseconds.

When the erl-script-timeout time was exceeded, the server incorrectly marked the answer as sent, thereby leaving client hanging (with an incomplete answer). This has been changed, so that now the socket will be closed.

[httpc|httpd] http_chunk data handling/passing improvement.

This is a modification to the http_chunk module to forward any full chunk received, regardless of whether the size field for the following chunk has been received yet. This allows http_chunk to be used in situations where a long term HTTP connection is used to send periodic status updates as individual chunks. Previously a given chunk would not be forwarded to the client process until the size for the next chunk had been read which rendered the module difficult to use for the scenario described.

[httpc] Several more or less critical fixes:

Initial call between the httpc manager and request handler was synchronous.

When the manager starts a new request handler, this is no longer a synchronous operation. Previously, the new request handler made the connection to the server and issuing of the first request (the reason for starting it) in the gen_server init function. If the connection for some reason "took some time", the manager hanged, leaving all other activities by that manager also hanging.

[httpd] The server did not fully support the documented module callback api. Specifically, the load function should be able to return the atom ok, but this was not accepted.

[ftpc] - The ls/2 function (LIST command) and the nlist/2 function (NLST command) with wildcards did not work properly.

These functions is documented as working on directories, but this is actually not according the standard. The LIST and NLST commands are specified to operate on a directory or other group of files, or a file.

Previously, an attempt was made to check if the listing returned by the server was actually an error message. This was done by changing remote directory (cd) into the (assumed) "directory". This may work if Pathname was actually a directory, but as this is not always the case, this test does not work. Instead, we now return the actual server result and leave the interpretation to the caller.

When starting the web-server either using a file with property list (the proplist_file) or a an property list, using the ipfamily option: {ipfamily, inet | inet6 | inet6fb4}.

Finally, when starting the web-server using the classical apache-style config file, the BindAddress directive has been augmented to allow the specification of the IpFamily: BindAddress blirk.ericsson.se|inet

Default is inet6fb4 which emulates the behaviour of the previous version.
