226c1c6876 imap: Added custom request perform and response handler functions 
Added imap_custom(), which initiates the custom command processing,
and an associated response handler imap_state_custom_resp(), which
handles any responses by sending them to the client as body data.

All untagged responses with the same name as the first word of the
custom request string are accepted, with the exception of SELECT and
EXAMINE which have responses that cannot be easily identified. An
extra check has been provided for them so that any untagged responses
are accepted for them.

ee7034800d imap: Added custom request parsing 
Added imap_parse_custom_request() for parsing the CURLOPT_CUSTOMREQUEST
parameter which URL decodes the value and separates the request from
any parameters - This makes it easier to filter untagged responses
by the request command.

ec38ac38c7 imap: Changed successful response logic in imap_state_append_resp() 
For consistency changed the logic of the imap_state_append_resp()
function to test for an unsucessful continuation response rather than a
succesful one.

7b471fb344 imap: Enabled APPEND support in imap_perform() 
Added logic in imap_perform() to perform an APPEND rather than SELECT
and FETCH if an upload has been specified.

f8c8c76d39 imap: Implemented APPEND final processing 
The APPEND operation needs to be performed in several steps:
  1) We send "<tag> APPEND <mailbox> <flags> {<size>}\r\n"
  2) Server responds with continuation respose "+ ...\r\n"
  3) We start the transfer and send <size> bytes of data
  4) Only now we end the request command line by sending "\r\n"
  5) Server responds with "<tag> OK ...\r\n"

This commit performs steps 4 and 5, in the DONE phase, as more
processing is required after the transfer.

b06a786226 imap: Updated the coding style for state changes after a send operation 
Some state changes would be performed after a failure test that
performed a hard return, whilst others would be performed within a test
for success. Updated the code, for consistency, so all instances are
performed within a success test.

025ba6e9be imap: Fixed error code returned for invalid FETCH response 
If the FETCH command does not result in an untagged response the the
UID is probably invalid. As such do not return CURLE_OK.

cdea86ff67 imap: Added processing of the final FETCH responses 
Not processing the final FETCH responses was not optimal, not only
because the response code would be ignored but it would also leave data
unread on the socket which would prohibit connection reuse.

974c663471 imap: Introduced FETCH_FINAL state for processing final fetch responses 
A typical FETCH response can be broken down into four parts:

  1) "* <uid> FETCH (<what> {<size>}\r\n", using continuation syntax
  2) <size> bytes of the actual message
  3) ")\r\n", finishing the untagged response
  4) "<tag> OK ...", finishing the command

Part 1 is read in imap_fetch_resp(), part 2 is consumed in the PERFORM
phase by the transfer subsystem, parts 3 and 4 are currently ignored.

c368fbcb10 imap: Added processing of more than one response when sent in same packet 
Added a loop to imap_statemach_act() in which Curl_pp_readresp() is
called until the cache is drained. Without this multiple responses
received in a single packet could result in a hang or delay.

91b2184e1b imap: Added a helper function for upcoming untagged response filtering 
RFC 3501 states that "the client MUST be prepared to accept any response
at all times" yet we assume anything received with "* " at the beginning
is the untagged response we want.

Introduced a helper function that checks whether the input looks like a
response to specified command, so that we may filter the ones we are
interested in according to the current state.
