test1522: add debug tracing

I used this to track down some issues and I figured I could just as well
keep this extra logging in here for future needs.

ftp: a 550 response to SIZE returns CURLE_REMOTE_FILE_NOT_FOUND

This is primarily interesting for cases where CURLOPT_NOBODY is set as
previously curl would not return an error for this case.

MDTM getting 550 now also returns this error (it returned
CURLE_FTP_COULDNT_RETR_FILE before) in order to unify return codes for
missing files across protocols and specific FTP commands.

libcurl already returns error on a 550 as a MDTM response (when
CURLOPT_FILETIME is set). If CURLOPT_NOBODY is not set, an error would
happen subsequently anyway since the RETR command would fail.

Add test 1913 and 1914 to verify. Updated several tests accordingly due
to the updated SIZE behavior.

dynbuf: introduce internal generic dynamic buffer functions

A common set of functions instead of many separate implementations for
creating buffers that can grow when appending data to them. Existing
functionality has been ported over.

In my early basic testing, the total number of allocations seem at
roughly the same amount as before, possibly a few less.

mime: do not perform more than one read in a row

Input buffer filling may delay the data sending if data reads are slow.
To overcome this problem, file and callback data reads do not accumulate
in buffer anymore. All other data (memory data and mime framing) are
considered as fast and still concatenated in buffer.
As this may highly impact performance in terms of data overhead, an early
end of part data check is added to spare a read call.
When encoding a part's data, an encoder may require more bytes than made
available by a single read. In this case, the above rule does not apply
and reads are performed until the encoder is able to deliver some data.

Tests 643, 644, 645, 650 and 654 have been adapted to the output data
changes, with test data size reduced to avoid the boredom of long lists of
1-byte chunks in verification data.
New test 667 checks mimepost using single-byte read callback with encoder.
New test 668 checks the end of part data early detection.

mime: latch last read callback status.

In case a read callback returns a status (pause, abort, eof,
error) instead of a byte count, drain the bytes read so far but
remember this status for further processing.
Takes care of not losing data when pausing, and properly resume a
paused mime structure when requested.
New tests 670-673 check unpausing cases, with easy or multi
interface and mime or form api.
