Continuing commit 0eb3d15c more return code variable name changes.

Added support for WinIDN build configurations to the VC8 and VC9
project files.

If Apple ever drops SSLv3 support from the Security framework, we'll fail with an error if the user insists on using SSLv3.

- Remove SSLv3 from SSL default in darwinssl, schannel, cyassl, nss,
openssl effectively making the default TLS 1.x. axTLS is not affected
since it supports only TLS, and gnutls is not affected since it already
defaults to TLS 1.x.

- Update CURLOPT_SSLVERSION doc

... for the local variable name in functions holding the return
code. Using the same name universally makes code easier to read and
follow.

Also, unify code for checking for CURLcode errors with:

 if(result) or if(!result)

instead of

 if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)

The variable is already assigned, skip the duplicate assignment.

Prefer usage of Perl modules for sha1 calculation since there
might be systems where openssl is not installed or not in path.
If openssl is used for sha1 calculation then dont rely on cut
since it is usually not available on other systems than Linux.

This is not actually used uninitialized but we silence warnings.

This fixes a connection failure when FTPS handle is reused.

Initial work to generate a pkg-config and curl-config script. Static
linking (`curl-config --static-libs` and `pkg-config --shared --libs
libcurl`) is broken and therefore disabled.

CONFIGURE_OPTIONS does not make sense for CMake, use an empty string
for now.

At least `curl-config --features` and `curl-config --protocols` work
which is needed by runtests.pl.

This matches the behavior from autotools. The auxiliary major, minor
and patch components are not needed anymore and therefore removed.

For compatibility with autoconf, it will be used later for curl-config
and pkg-config. Not all features and or protocols can be enabled as
these are missing additional checks (see new TODOs).

SUPPORT_PROTOCOLS is partially scripted (grep for SUPPORT_PROTOCOLS=)
and manually verified/modified. SUPPORT_FEATURES is manually added.
