parser.y: fix assoc of -> and < > <= >=
The parser allowed senseless `a > b > c` but disallowed `a -> b -> c` which seems valid
It might be a typo

prim_foldlStrict: call forceValue() before value is copied
forceValue() were called after a value is copied effectively forcing only one of the copies keeping another copy not evaluated.
This resulted in its evaluation of the same lazy value more than once (the number of hits is not big though)

Will Dietz 4495560d6d Revert "progress-bar: re-draw last update if nothing new for 1sec."
Not ready for this yet, causes the prompt to disappear in nix repl
and more generally can overwrite non-progress-bar messages.

This reverts commit 44de71a396.

nix-prefetch-url: Download file in constant memory
Before:

  $ command time nix-prefetch-url https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.6.tar.xz
  1.19user 1.02system 0:41.96elapsed 5%CPU (0avgtext+0avgdata 182720maxresident)k

After:

  1.38user 1.05system 0:39.73elapsed 6%CPU (0avgtext+0avgdata 16204maxresident)k

Note however that addToStore() can still take a lot of memory
(e.g. RemoteStore::addToStore() is constant space, but
LocalStore::addToStore() isn't; that's fixed by
c94b4fc7ee
though).

Fixes #1400.

nix-daemon: Respect --store
For example, this allows you to do run nix-daemon as a non-privileged
user:

  eelco$ NIX_STATE_DIR=~/my-nix/nix/var nix-daemon --store ~/my-nix/

The NIX_STATE_DIR is still needed because settings.nixDaemonSocketFile
is not derived from settings.storeUri (and we can't derive it from the
store's state directory because we don't want to open the store in the
parent process).

search.cc: improve UX for nix search
As proposed in #1634 the `nix search` command could use some
improvements. Initially 0413aeb35d added
some basic sorting behavior using `std::map`, a next step would be an
improvement of the output.

This patch includes the following changes:

* Use `$PAGER` for outputs with `RunPager` from `shared.hh`:
  The same behavior is defined for `nix-env --query`, furthermore it
  makes searching huge results way easier.

* Simplified result blocks:
  The new output is heavily inspired by the output from `nox`, the first
  line shows the attribute path and the derivaiton name
  (`attribute path (derivation name)`) and the description in the second
  line.

Will Dietz 44de71a396 progress-bar: re-draw last update if nothing new for 1sec.
Slightly nicer behavior when updates are somewhat far apart
(during a long linking step, perhaps) ensuring things
don't appear unresponsive.

If we wait the maximum amount for the update,
don't bother waiting another 50ms (for rate-limiting purposes)
and just check if we should quit.

This also ensures we'll notice the request to quit within 1s
if quit is signalled but there is not an udpate.
(I'm not sure if this happens or not)

Fix optimise-store.cc to skip more paths on macOS
I hate to make this such a large check but the lack of documentation means we really have no idea what's allowed. All of them reported so far have been within ".app/Contents" directories. That appears to be a safe starting point. However, I would not be surprised to also find more paths that are disallowed for instance in .framework or .bundle directories.

nix: Remove special handling of .drv files
This makes 'nix copy' and 'nix path-info' work on .drv store
paths. Removing special treatment of .drv files seems the most
future-proof approach given the possible removal of .drv files in the
future.

Note that 'nix build' will still build (rather than substitute) .drv
paths due to the unfortunate overloading in Store::buildPaths().

Move EvalState from the stack to the heap
EvalState contains a few counters (e.g. nrValues) that increase
quickly enough that they end up being interpreted as pointers by the
garbage collector. Moving it to the heap makes them invisible to the
garbage collector.

This reduces the max RSS doing 100 evaluations of
nixos.tests.firefox.x86_64-linux.drvPath from 455 MiB to 292 MiB.

Note: ideally, allocations would be much further up in the 64-bit
address space to reduce the odds of an integer being misinterpreted as
a pointer. Maybe we can use some linker magic to move the .bss segment
to a higher address.

Don't scan for roots in dynamic libraries
This reduces the risk of object liveness misdetection. For example,
Glibc has an internal variable "mp_" that often points to a Boehm
object, keeping it alive unnecessarily. Since we don't store any
actual roots in global variables, we can just disable data segment
scanning.

With this, the max RSS doing 100 evaluations of
nixos.tests.firefox.x86_64-linux.drvPath went from 718 MiB to 455 MiB.
