Shea Levy 136f2f7046 Add the ExprBuiltin Expr type to the AST
Certain desugaring schemes may require the parser to use some builtin
function to do some of the work (e.g. currently `throw` is used to
lazily cause an error if a `<>`-style path is not in the search path)
Unfortunately, these names are not reserved keywords, so an expression
that uses such a syntactic sugar will not see the expected behavior
(see tests/lang/eval-okay-redefine-builtin.nix for an example).

This adds the ExprBuiltin AST type, which when evaluated uses the value
from the rootmost variable scope (which of course is initialized
internally and can't shadow any of the builtins).

Eelco Dolstra b352fe2775 Revert "Scan /proc/<pid>/cmdline for GC roots"
This reverts commit 194e3374b8.
Checking the command line for GC roots means that

  $ nix-store --delete $path

will fail because $path is now a root because it's mentioned on the
command line.

Petr Rockai f1e5dedb61 perl: Call loadConfFile() in doInit to avoid screwing sqlite journal mode.
If the database is opened through perl bindings (and even though nix.conf has
use-sqlite-wal set to false), the database is automatically converted into WAL
mode. This makes the next nix process to access the database convert it back to
"truncate". If the database is still open at the time in wal mode by the perl
program, this fails and crashes the nix doing the wal -> truncate conversion.

Shea Levy e36229d27f Bump language version for new storePath feature
This will allow e.g. channel expressions to use builtins.storePath IFF
it is safe to do so without knowing if the path is valid yet.

Eelco Dolstra e9b6397d2f Add a rule for creating directories
The tricky thing here is that if you have a directory as a

("dir/prog: stuff | dir"), otherwise the target will be rebuilt every
time because the timestamp on the directory keeps changing.

Eelco Dolstra 2bd0fcc966 Use libnix as a prefix for all Nix libraries
In particular "libutil" was always a problem because it collides with
Glibc's libutil.  Even if we install into $(libdir)/nix, the linker
sometimes got confused (e.g. if a program links against libstore but
not libutil, then ld would report undefined symbols in libstore
because it was looking at Glibc's libutil).
