7ab4e7adb9 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).

9dfb194833 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.

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.

url: fix alignment of ssl_backend_data struct
- Align the array of ssl_backend_data on a max 32 byte boundary.

8 is likely to be ok but I went with 32 for posterity should one of
the ssl_backend_data structs change to contain a larger sized variable
in the future.

Prior to this change (since dev 70f1db3, release 7.56) the connectdata
structure was undersized by 4 bytes in 32-bit builds with ssl enabled
because long long * was mistakenly used for alignment instead of
long long, with the intention being an 8 byte boundary. Also long long
may not be an available type.

The undersized connectdata could lead to oob read/write past the end in
what was expected to be the last 4 bytes of the connection's secondary
socket https proxy ssl_backend_data struct (the secondary socket in a
connection is used by ftp, others?).

fa64b0fc4b content_encoding: fix inflate_stream for no bytes available
- Don't call zlib's inflate() when avail_in stream bytes is 0.

This is a follow up to the parent commit 19e66e5. Prior to that change
libcurl's inflate_stream could call zlib's inflate even when no bytes
were available, causing inflate to return Z_BUF_ERROR, and then
inflate_stream would treat that as a hard error and return
CURLE_BAD_CONTENT_ENCODING.

According to the zlib FAQ, Z_BUF_ERROR is not fatal.

This bug would happen randomly since packet sizes are arbitrary. A test
of 10,000 transfers had 55 fail (ie 0.55%).

979d2877be transfer: Fix chunked-encoding upload bug
- When uploading via chunked-encoding don't compare file size to bytes
  sent to determine whether the upload has finished.

Chunked-encoding adds its own overhead which why the bytes sent is not
equal to the file size. Prior to this change if a file was uploaded in
chunked-encoding and its size was known it was possible that the upload
could end prematurely without sending the final few chunks. That would
result in a server hang waiting for the remaining data, likely followed
by a disconnect.

The scope of this bug is limited to some arbitrary file sizes which have
not been determined. One size that triggers the bug is 475020.
