1c400b4e5e zlib: ensure user provided memory functions are used by zlib, when given 
As a bonus, this lets our MemoryTracking subsystem track zlib operations.
And also fixes a shortcut some zlib 1.2.x versions took using malloc()
instead of calloc(), which would trigger memory debuggers warnings on
memory being used without having been initialized.

7764795c06 follow redirect: ignore response-body on redirect even if compressed 
Sebastian V reported bug #3000056 identifying a problem with
redirect following. It showed that when curl followed redirects
it didn't properly ignore the response body of the 30X response
if that response was using compressed Content-Encoding!

06ae8ca5a6 - When downloading compressed content over HTTP and the app as asked libcurl 
to automatically uncompress it with the CURLOPT_ENCODING option, libcurl
  could wrongly provide the callback with more data than what the maximum
  documented amount. An application could thus get tricked into badness if the
  maximum limit was trusted to be enforced by libcurl itself (as it is
  documented).

  This is further detailed and explained in the libcurl security advisory

242a17b9e0 - Balint Szilakszi reported a memory leak when libcurl did gzip decompression 
of streams that had some parts (legitimately) missing. We now provide and use
  a proper cleanup function for the content encoding submodule.

4ad296c60b - A second follow-up change by Andre Guibert de Bruet to fix a related memory 
leak like that fixed on the 14th. When zlib returns failure, we need to
  cleanup properly before returning error.

13648f8ccd struct HandleData is now called struct SingleRequest, and is only for data that 
is inited at the start of the DO action. I removed the Curl_transfer_keeper
struct completely, and I had to move out a few struct members (that had to
be set before DO or used after DONE) to the UrlState struct. The SingleRequest
struct is accessed with SessionHandle->req.

One of the biggest reasons for doing this was the bunch of duplicate struct
members in HandleData and Curl_transfer_keeper since it was really messy to
keep track of two variables with the same name and basically the same purpose!

9bf9617ad6 Fix compiler warnings 
"case label value exceeds maximum value for type" and
"comparison is always false due to limited range of data type"

Both triggered when using a bool variable as the switch variable
in a switch statement and using enums for the case targets.

87c5ed8bec Paul Querna fixed libcurl to better deal with deflate content encoding when 
the stream (wrongly) lacks a proper zlib header. This seems to be the case on
too many actual server implementations.
