Rationale: when starting up a curl-using app, all cookies from the jar
are checked against each other. This was causing a startup delay in the
Fifth browser.

All tests pass.

Apparently there are sites out there that do redirects to URLs they
provide in plain UTF-8 or similar. Browsers and wget %-encode such
headers when doing a subsequent request. Now libcurl does too.

Added test 1138 to verify.

Closes #425

Fixes a name space pollution at the cost of programs using one of these
defines will no longer compile. However, the vast majority of libcurl
programs that do multipart formposts use curl_formadd() to build this
list.

This reverts commit 370ee919.

Issue #509 has all the details but it was confirmed that the crash was
not due to this, so the previous commit was wrong.

... as the certificate is strictly speaking not private.

After a successful call to SSL_CTX_use_PrivateKey(), we must not call
EVP_PKEY_free() on the key.

Out of date and not kept accurate. It was sort of a problem of the past
anyway.

- Allow the user to use PKG_CONFIG but not PKGCONFIG.

Background:

Last week in 14d5a86b a change was made to allow the user to set the
PKGCONFIG variable. Today in 72d99f2e I supplemented that to allow the
more common PKG_CONFIG as an alternative if PKGCONFIG is not set.

Neither of those changes worked as expected because PKGCONFIG is
occasionally reset in configure and by the CURL_CHECK_PKGCONFIG macro.
Instead in this commit I take the approach that the user may set
PKG_CONFIG only.

- If mingw ssl make sure -lgdi32 comes after ssl libs

- Allow PKG_CONFIG to set pkg-config location and options

This allows FTP transfers with growing (or shrinking) files without

... and add a little example of what the weight actually means. "Relative
proportion of bandwidth".

Removed wrong assert()s

The 'conn' passed in as userdata can be used and there can be other
sessionhandles ('data') than the single one this checked for.

- Add a VPATH-statement for the vtls/*.c files.

- Due to 'vtls/*.c', remove that subdir part from $(OBJECTS).

... noticed with mbedTLS.

closes #496

- Use CURL_BINARY_DIR instead of CMAKE_BINARY_DIR.

When including CURL using add_subdirectory the variables
CMAKE_BINARY_DIR and CURL_BINARY_DIR hold different paths.
