  attributes is present.

SSL_CTX_add_extra_chain_cert takes ownership of the given certificate
while, despite the similar name, SSL_CTX_add_client_CA does not. Thus
it's best to call SSL_CTX_add_client_CA before
SSL_CTX_add_extra_chain_cert, while the code still has ownership of the
argument.

This bugfix is similar to commit c111178b.

This repairs cookies for localhost.

Non-PSL builds will now only accept "localhost" without dots, while PSL
builds okeys everything not listed as PSL.

Added test 1258 to verify.

This was a regression brought in a76825a5

Support is trickling in already.

The winbuild/ build files is now the single MSVC makefile build choice.

Closes #1215

On Windows it's possible to have input files with CRLF line endings and
a perl that defaults to LF line endings (eg msysgit). Currently that
results in generator output of mixed line endings of CR, LF and CRLF.

This change fixes that issue in the most succinct way by opening the
files in :crlf text mode even when the perl being used does not default
to that mode. (On operating systems that don't have a separate text mode
it's essentially a no-op.) The output continues to be in the perl's
native line ending.

When using multi, mbedtls handshake is in non blocking mode.  vtls must
set wait for read/write flags for the socket.

Closes #1223

Replace use of fixed macro BUFSIZE to define the size of the receive
buffer.  Reappropriate CURLOPT_BUFFERSIZE to include enlarging receive
buffer size.  Upon setting, resize buffer if larger than the current
default size up to a MAX_BUFSIZE (512KB). This can benefit protocols
like SFTP.

Fix compile warnings that appeared only when curl has been configured
with '--disable-verbose'.

Regression since 1d4202ad, which moved the buffer into a more narrow
scope, but the data in that buffer was used outside of that more narrow
scope.

- Fix logic error in Curl_ossl_random.

Broken a few days ago in 807698db.

By supporting this, subsequent connects would load a lot less data from
disk.
