Prevent modification of easy handle being added with curl_multi_add_handle()
unless this function actually suceeds.
Run Curl_posttransfer() to allow restoring of SIGPIPE handler when
Curl_connect() fails early in multi_runsingle().
It makes much nicer and less convuluted code everywhere if this struct
member is always present even when libcurl is built without SSL support.
This reverts parts of commit 15e3e45170
Modified smtp_endofresp() to detect NTLM from the server specified list
of supported authentication mechanisms.
Modified smtp_authenticate() to start the sending of the NTLM data.
Added smtp_auth_ntlm_type1_message() which creates a NTLM type-1
message. This function is used by authenticate() to start the sending
of data and by smtp_state_auth_ntlm_resp() when the AUTH command
doesn't contain the type-1 message as part of the initial response.
This lack of initial response can happen if an OOM error occurs or the
type-1 message is longer than 504 characters. As the main AUTH command
is limited to 512 character the data has to be transmitted in two
parts; one containing the AUTH NTLM and the second containing the
type-1 message.
Added smtp_state_auth_ntlm_type2msg_resp() which handles the incoming
type-2 message and sends an outgoing type-3 message. This type-2
message is sent by the server in response to our type-1 message.
Modified smtp_state_auth_resp() to handle the response to: the AUTH
NTLM without the initial response and the type-2 response.
Modified smtp_disconnect() to cleanup the NTLM SSPI stack.
Added the output message length as a parameter to both
Curl_ntlm_create_type1_message() and Curl_ntlm_create_type3_message()
for use by future functions that require it.
Updated curl_ntlm.c to cater for the extra parameter on these two
functions.
Changed the name of variable l, in several functions, which represents
the length of strings being sent to the server, to len which is more
meaningful and consistent with other code in smtp.c and elsewhere.
Reworked smtp_authenticate() to be simpler and easier to follow.
Variables and now initialised in their definitions and if no username
and password are specified the function sets the state to SMTP_STOP and
returns immediately, rather than being part of a huge if statement.
Don't even declare the struct members for disabled features
Introducing the CURLSHE_NOT_BUILT_IN return code for the share interface
when trying to set a sharing option that has been disabled (or not
enabled) in the library.
When the progress function returns to cancel the request, we must mark
the connection to get closed and it must do to the DONE state.
do_init() must be called as early as possible so that state variables
for new connections are reset early. We could otherwise see that the old
values were still there when a connection was to be disconnected very
early and it would make it behave wrongly.
Bug: http://curl.haxx.se/mail/lib-2011-10/0006.html
Reported by: Vladimir Grishchenko
The size of the email can now be set via CURLOPT_INFILESIZE. This
allows the email to be rejected by the server, if supported, and the
maximum size has been configured on the server.
Removed the code that striped off the domain name when Curl_gethostname
returned the fully qualified domain name as the function has been
updated to return the un-qualified host name.
Replaced the use of HOSTNAME_MAX as the size of the buffer in the call
to Curl_gethostname with sizeof(host) as this is safer should the buffer
size ever be changed.
Allow (*curl_write_callback) write callbacks to return
CURL_WRITEFUNC_OUT_OF_MEMORY to properly indicate libcurl of OOM conditions
inside the callback itself.
If a socket is larger than FD_SETSIZE, avoid using FD_SET() on the
platforms where this is possible.

To avoid that the progress meter headers get output between each
transfer, make sure the bits gets kept when (re-)inited.
Reported by: Christopher Stone
I think curl should ignore this case and smtp.c should test for this.
Since RFC-2821 seems to allow a "null reverse-path". Ref. "MAIL
FROM:<>" in section 3.7, page 25.
Fixed Curl_gethostname() so that it always returns the un-qualified
machine name rather than being dependent on the socket provider.
Note: The return of getenv("CURL_GETHOSTNAME") is also parsed in case
the developer / test harness provided a fully qualified domain name as
it's value as well.
