In HTTP 1.1, the client can send the header "Expect: 100-continue", which
tells the server that the client isn't going to send the body until the
server tells it to by sending a "continue" response (HTTP response code 100).
The server is obligated to send that response.
However, many servers are broken and don't send the Continue response.
Early libcurl did not send the Expect: header, thus worked fine with such
broken servers. But as of ca. 2007, libcurl sends the Expect:, and waits
for the response, when the body is large. It gives up after 3 seconds and
sends the body anyway.
To accomodate the broken servers and for backward compatibility, we always
force libcurl not to send the Expect and consequently not to wait for the
response, using the hackish (but according to libcurl design) method of
including an entry in our explicit header list that is an Expect: header
with an empty argument. This causes libcurl not to send any Expect: header.
This is since 1.19; we may find there are also servers and/or libcurl levels
that can't work with that.
We may find a case where the Expect/Continue protocol is desirable. If we
do, we should add a transport option to request the function and let libcurl
do its thing when the user requests it.
The purpose of Expect/Continue is to save the client the trouble of
generating and/or sending the body when the server is just going to reject
the transaction based on the headers -- like maybe because the body is
too big.

This is a Curl "progress function." It's something various Curl functions
call every so often, including whenever something gets interrupted by the
process receiving, and catching, a signal. There are two purposes of a
Curl progress function: 1) lets us log the progress of a long-running
transaction such as a big download, e.g. by displaying a progress bar
somewhere. 2) allows us to tell the Curl function, via our return code,
that calls it that we don't want to wait anymore for the operation to
complete.
In Curl versions before March 2007, we get called once per second and
signals have no effect. In current Curl, we usually get called immediately
after a signal gets caught while Curl is waiting to receive a response from
the server. But Curl doesn't properly synchronize with signals, so it may
miss one and then we don't get called until the next scheduled
one-per-second call.
All we do is pass the call through to the curlTransaction's progress
function (the one that the creator of the curlTransaction registered).
This function is not as important as it once was for interrupting purposes.
This module used to use curl_easy_perform(), which can be interrupted only
via this progress function. But because of the above-mentioned failure of
Curl to properly synchronize signals (and Bryan's failure to get Curl
developers to accept code to fix it), we now use the Curl "multi" facility
instead and do our own pselect(). But This function still normally gets
called by curl_multi_perform(), which the transport tries to call even when
the user has requested interruption, because we don't trust our ability to
abort a running Curl transaction. curl_multi_perform() reliably winds up a
Curl transaction when this function tells it to.
