Fixes #2230
Closes #2233

Prior to this change the stored byte count of each trailer was
miscalculated and 1 less than required. It appears any trailer
after the first that was passed to Curl_client_write would be truncated
or corrupted as well as the size. Potentially the size of some
subsequent trailer could be erroneously extracted from the contents of
that trailer, and since that size is used by client write an
out-of-bounds read could occur and cause a crash or be otherwise
processed by client write.

The bug appears to have been born in 0761a51e (precedes 7.49.0).

Closes https://github.com/curl/curl/pull/2231

Before calling Curl_client_chop_write(), change the owner of connection
to the current Curl_easy handle. This will fix the issue #2217.

This reverts commit c97648b5.

SIZEOF_LONG should not be checked in system.h since that macro is only
defined when building libcurl.

Bug: https://curl.haxx.se/mail/lib-2017-12/0074.html

Decoding loop implementation did not concern the case when all
received data is consumed by Brotli decoder and the size of decoded
data internally hold by Brotli decoder is greater than CURL_MAX_WRITE_SIZE.
For content with unencoded length greater than CURL_MAX_WRITE_SIZE this
can result in the loss of data at the end of content.

Closes #2194

- Ignore X509_R_CERT_ALREADY_IN_HASH_TABLE errors in the CTX callback
  since it's possible the cert may have already been loaded by libcurl.

- Remove the EXAMPLE code in the CURLOPT_SSL_CTX_FUNCTION.3 doc.
  Instead have it direct the reader to this cacertinmem.c example.

- Fix the CA certificate to use the right CA for example.com, Digicert.

- Move the size modifier detection code from limit-rate to its own
  function so that it can also be used with max-filesize.

Size modifiers are the suffixes such as G (gigabyte), M (megabyte) etc.

For example --max-filesize 1G

Move curl_mime_initpart() and curl_mime_cleanpart() calls to lower-level
functions dealing with UserDefined structure contents.
This avoids memory leakages on curl-generated part mime headers.
New test 2073 checks this using the cli tool --next option: it
triggers a valgrind error if bug is present.

- When zlib version is < 1.2.0.4, process gzip trailer before considering
extra data as an error.
- Inflate with Z_BLOCK instead of Z_SYNC_FLUSH to maximize correct data
and minimize corrupt data output.
- Do not try to restart deflate decompression in raw mode if output has
started or if the leading data is not available anymore.
- New test 232 checks inflating raw-deflated content.

Some error codes were not yet defined in brotli 0.6.0: do not issue code

[ci skip]

scan-build would warn on a potential access of an uninitialized
buffer. I deem it a false positive and had to add this somewhat ugly
work-around to silence it.

A scan-build warning.

This broke in 07cb27c9. Make sure to return 'result' properly. Pointed
out by scan-build!

Closes #2173

Fixed undefined symbol of getenv() which does not exist when compiling
for Windows 10 App (CURL_WINDOWS_APP). Replaced getenv() with
curl_getenv() which is aware of getenv() absence when CURL_WINDOWS_APP
is defined.
