- David McCreedy brought a fix and a new test case (129) to make libcurl work
again when downloading files over FTP using ASCII and it turns out that the
final size of the file is not the same as the initial size the server
reported. This is very common since servers don't take the newline
conversions into account.

- Gil Weber reported a peculiar flaw with the multi interface when doing SFTP
transfers: curl_multi_fdset() would return -1 and not set and file
descriptors several times during a transfer of a single file. It turned out
to be due to two different flaws now fixed. Gil's excellent recipe helped me
nail this.

- Johan van Selst found and fixed a OpenSSL session ref count leak:

ossl_connect_step3() increments an SSL session handle reference counter on
each call. When sessions are re-used this reference counter may be
incremented many times, but it will be decremented only once when done (by
Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
if this reference count remains positive. When a session is re-used the
reference counter should be corrected by explicitly calling
SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
introducing a memory leak.

- Make curl support --ssl and --ssl-reqd instead of the previous FTP-specific
versions --ftp-ssl and --ftp-ssl-reqd as these options are now used to
control SSL/TLS for IMAP, POP3 and SMTP as well in addition to FTP. The old
option names are still working but the new ones are the prefered ones
(listed and documented).

- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This
command is a special "hack" used by the drftpd server, but even though it is
a custom extension I've deemed it fine to add to libcurl since this server
seems to survive and people keep using it and want libcurl to support
it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
usable from the curl tool with --ftp-pret. Using this option on a server
that doesn't support this command will make libcurl fail.

- Jon Nelson found a regression that turned out to be a flaw in how libcurl
detects and uses proxies based on the environment variables. If the proxy
was given as an explicit option it worked, but due to the setup order
mistake proxies would not be used fine for a few protocols when picked up
from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
test case 1106 that verifies this functionality.

- Siegfried Gyuricsko found out that the curl manual said --retry would retry
on FTP errors in the transient 5xx range. Transient FTP errors are in the

Now the retry code retries on all FTP transfer failures that ended with a
4xx response.

least) doesn't handle this properly. Martin Storsjo provided the fix!

The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
the command line.

though it failed to write a very small download to disk (done in a single
fwrite call). It turned out to be because fwrite() returned success, but
there was insufficient error-checking for the fclose() call which tricked
curl to believe things were fine.
