brotli: data at the end of content can be lost
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.

curl_easy_reset: release mime-related data.
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.

content_encoding: rework zlib_inflate
- 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

- 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.

rand: add a clang-analyzer work-around

vtls: replaced getenv() with curl_getenv()
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.
It was actually added rather recently in 8e8afa82cbb629 due to a crash
that would otherwise happen in the RTSP code. As I don't think we've
fixed that behavior yet, we better keep this work-around until we have
fixed it better.

openssl: Disable file buffering for Win32 SSLKEYLOGFILE
Prior to this change SSLKEYLOGFILE used line buffering on WIN32 just
like it does for other platforms. However, the Windows CRT does not
actually support line buffering (_IOLBF) and will use full buffering
(_IOFBF) instead. We can't use full buffering because multiple processes
may be writing to the file and that could lead to corruption, and since
full buffering is the only buffering available this commit disables
buffering for Windows SSLKEYLOGFILE entirely (_IONBF).

openssl: improve data-pending check for https proxy
- Allow proxy_ssl to be checked for pending data even when connssl does
not yet have an SSL handle.
This change is for posterity. Currently there doesn't seem to be a code
path that will cause a pending data check when proxyssl could have
pending data and the connssl handle doesn't yet exist [1].
[1]: Recall that an https proxy connection starts out in connssl but if
the destination is also https then the proxy SSL backend data is moved
from connssl to proxyssl, which means connssl handle is temporarily
empty until an SSL handle for the destination can be created.

Connections that are used for HTTP/1.1 Pipelining or HTTP/2 multiplexing
only get additional transfers added to them if the existing connection

HTTP/2 streams in different threads using a shared connection.

libssh2: remove dead code from SSH_SFTP_QUOTE
Figured out while reviewing code in the libssh backend. The pointer was
checked for NULL after having been dereferenced, so we know it would
always equal true or it would've crashed.
This SFTP test fails with libssh back-end due to failure to verify
the peer. Disable peer verification in the test as there seems to
be the intention of the test.
Note that the libssh back-end automatically verifies the peer's
host using the default known_hosts file.
libssh2: send the correct CURLE error code on scp file not found
That also updates tests to expect the right error code
libssh2 back-end returns CURLE_SSH error if the remote file
is not found. Expect instead CURLE_REMOTE_FILE_NOT_FOUND
which is sent by the libssh backend.

lib: don't export all symbols, just everything curl_*
Absent any 'symbol map' or script to limit what gets exported, static
linking of libraries previously resulted in a libcurl with curl's and
those other symbols being (re-)exported.
This did not happen if 'versioned symbols' were enabled (which is not
the default) because then a version script is employed.
This limits exports to everything starting in 'curl_*'., which is
what "libcurl.vers" exports.
This avoids strange side-effects such as with mixing methods
from system libraries and those erroneously offered by libcurl.
SSL: Avoid magic allocation of SSL backend specific data
Originally, my idea was to allocate the two structures (or more
precisely, the connectdata structure and the four SSL backend-specific
strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so
that they all could be free()d together.
However, getting the alignment right is tricky. Too tricky.
So let's just bite the bullet and allocate the SSL backend-specific
data separately.
As a consequence, we now have to be very careful to release the memory
allocated for the SSL backend-specific data whenever we release any
connectdata.
