Get rid of stdout redirection to NUL and move stderr redirection
into RM and RMDIR macros.

Check for BCCDIR environment var done now as other checks.

Borland's $(MAKEDIR) expands to the path where make.exe is located,
use this feature to define BCCDIR when user has not defined BCCDIR.

The idea that the protocol and socktype is part of name resolving in the
libc functions is nuts. We keep the name resolver functions assume
TCP/STREAM and we make sure that when we want to connect to a UDP
service we use the correct UDP/DGRAM set instead. This bug was because
the ->protocol field was not always set correctly.

This bug was only affecting ipv6-disabled non-cares non-threaded builds.

Only under Windows

CMake/CheckTypeSize.c.in and CMake/CheckTypeSize.cmake were removed in
the previous cmake commit

This makes it possible to skip the call to unit_stop() in such
cases.  Also use Curl_safefree() in unit test 1302 so it will
pass the memory torture test.

The just added speedcheck must not ruin the error code if already set
due to a problem.

The CheckTypeSize module that comes with CMake 2.6.2 and above does
everything we need and also supports cross-compiling.  Avoid duplicating
an older version of it here.  This also fixes a cross-compiling error
because the old line

  include ("${CMAKE_MODULE_PATH}/CheckTypeSize.cmake")

failed because CMAKE_MODULE_PATH is a search path and not a directory.

Check for speedcheck limits during the state machine traversals

I came up with 33 different ways to call it and verify that it returns the
correct return code.

fail is a new function/macro that a test case can use to indicate a test
failure for cases when the standard macros are not sufficient.

As the function doesn't really use the connectdata struct but only the
SessionHanadle struct I modified what argument it wants.

This check verifies that a pointer contains the correct data.

512 bytes turned out too short for some data, so now we allocate a
larger buffer instead
