These were missed in commit c468c27b.

Embedded manifest option didn't work due to incorrect path.

When working on this code I found the previous setup a bit weird while
using proper defines increases readability.

Closes #1824

It is a defined possible greeting at server startup that means the
connection is already authenticated. See
https://tools.ietf.org/html/rfc3501#section-7.1.4

Test 846 added to verify.

Recent changes that replaced CURL_SIZEOF_LONG in the source with
SIZEOF_LONG broke builds that use the premade configuration files and
don't have SIZEOF_LONG defined.

Bug: #1816

The previous message was just too long for ordinary people and it was
encouraging users to use `--insecure` a little too easy.

By default, the MinGW CRT globs command-line arguments. This prevents
getting a single asterisk into an argument as test 1299 does. Turn off
globbing by setting the global variable _CRT_glob to 0 for MinGW.

libidn was replaced with libidn2 last year in configure.
Caveat: libidn2 may depend on a list of further libs.
These can be manually specified via CURL_LDFLAG_EXTRAS.

Closes #1808

Commit 5c2aac71 didn't work in the case of mixed-case keywords given on
the command-line.

This ensures that global data allocations are freed so Valgrind stays
happy. This was a problem with at least PolarSSL and mbedTLS.

Since curl 7.55.0, NetworkManager almost always failed its connectivity
check by timeout. I bisected this to 5113ad04 (http-proxy: do the HTTP
CONNECT process entirely non-blocking).

This patch replaces !Curl_connect_complete with Curl_connect_ongoing,
which returns false if the CONNECT state was left uninitialized and lets
the connection continue.
