tests/Makefile.am: remove wildcard usage in EXTRA_DIST
tests/libtest/Makefile.inc: sort build targets
build: use per-target '_CPPFLAGS' for those currently using default

Automake documents that doing this will make it choose a different name
for intermediate object files even when sharing source files across
targets of same Makefile.am.

Up to automake 1.13.1 target's intermediate object files were placed
in the build subdirectory of the target. We depended on this, probably
undocumented behavior, to achieve same behavior as if a per-target flag
had been specified when building targets that actually belong to
different Makefile.am files.

It seems automake 1.13.2 is going to break behavior mentioned above.

So, lets use a documented behavior in order to achieve same purpose,
across automake versions, no matter where automake wishes to place
intermediate object files.

Our build targets that already were using a per-target '_CFLAGS' or
'_CPPFLAGS' need no 'fixing', these were already 'fixed'. The only
Makefile.am or Makefile.in files in libcurl's source tree touched by
this 'fix' are tests/libtest/Makefile.inc and tests/unit/Makefile.inc.

--libcurl: fix for non-zero default options

If the default value for an option taking a long as its value is non
zero, and it is set by zero by a command line option, then that command
line option is not reflected in --libcurl's output. This is because line
520-521 of tool_setopt.c look like:

if(!lval)
    skip = TRUE;

An example of a command-line option doing so is the -k option that sets
CURLOPT_SLL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST to 0L, when the
defaults are non-zero.
url.c: fix HTTP CONNECT tunnel establishment upon delayed response

Fixes initial proxy response being processed by the tunneled protocol
handler instead of the HTTP wrapper handler. This issue would trigger
upon delayed CONNECT response from the proxy.

Additionally fixes a multi interface code-path in which connections
would not time out properly.

This does not fix known bug #39.

always-multi: always use non-blocking internals

Remove internal separated behavior of the easy vs multi intercace.
curl_easy_perform() is now using the multi interface itself.

Several minor multi interface quirks and bugs have been fixed in the
process.
