4dee289550 * In environments, store pointers to values rather than values. This
improves GC effectiveness a bit more (because a live value doesn't
  keep other values in the environment plus the parent environments
  alive), and removes the need for copy nodes.

41c45a9b31 * Store Value nodes outside of attribute sets. I.e., Attr now stores
a pointer to a Value, rather than the Value directly.  This improves
  the effectiveness of garbage collection a lot: if the Value is
  stored inside the set directly, then any live pointer to the Value
  causes all other attributes in the set to be live as well.

7119d38287 * In the referrers test, lower the nesting depth from 2500 to 1000 to
prevent hitting a stack overflow bug in the garbage collector.

705868a8a9 * Make sure that config.h is included before the system headers,
because it defines _FILE_OFFSET_BITS.  Without this, on 
  OpenSolaris the system headers define it to be 32, and then 
  the 32-bit stat() ends up being called with a 64-bit "struct 
  stat", or vice versa.

  This also ensures that we get 64-bit file sizes everywhere.

* Remove the redundant call to stat() in parseExprFromFile().
  The file cannot be a symlink because that's the exit condition
  of the loop before.

450837bcc8 * In printMsg(), ignore failing writes to stderr if we're in an
exception handler, otherwise throw an exception.  We need to ignore
  write errors in exception handlers to ensure that cleanup code runs
  to completion if the other side of stderr has been closed
  unexpectedly.

315d8fbd75 * Set the default system filter to "*". This ensures that (for
instance) "nix-env -i wine" works on x86_64-linux, even though Wine
  is built on i686-linux.  In the event that there are multiple
  matching derivations, prefer those built for the current system.

60b632b173 tests/build-hook.hook.sh: prefer more portable ... syntax over $(...) for running sub-shells
The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running
sub-shells. Consequently, this test fails on Solaris. To remedy the situation,
the script either needs to be run by /bin/bash -- which is non-standard --, or
it needs to use the ancient but portable `...` syntax.

a0d29040f7 Revert "configure.ac: make flex and bison required programs"
This reverts commit 22405. Apparently, these programs aren't necessarily
required when building from a release archive.

a17071fef1 Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared.
An "using namespace std" was added locally in those functions that refer to
names from <cstring>. That is not pretty, but it's a very portable solution,
because strcpy() and friends will be found in both the 'std' and in the global
namespace.

8b7f8b56f1 Added support for passing an (impure) NIX_BUILD_CORES variable to build expressions.
This patch adds the configuration file variable "build-cores" and the
command line argument "--cores". These settings specify the number of
CPU cores to utilize for parallel building within a job, i.e. by passing
an appropriate "-j" flag to GNU Make. The default value is 1, which
means that parallel building is *disabled*. If the number of build cores
is specified as 0 (synonymously: "guess" or "auto"), then the actual
value is supposed to be auto-detected by builders at run-time, i.e by
calling the nproc(1) utility from coreutils.

The environment variable $NIX_BUILD_CORES is available to builders, but
the contents of that variable does *not* influence the hash that goes
into the $out store path, i.e. the number of build cores to be utilized
can be changed at will without requiring any re-builds.
