nix: Respect -I, --arg, --argstr 
Also, random cleanup to argument handling.

Pass all settings to build-remote 
This ensures that command line flags such as --builders get passed
correctly.

Fix a hang in ThreadPool 
The worker threads could exit prematurely if they finished processing
all items while the main thread was still adding items. In particular,
this caused hanging nix-store --serve processes in the build farm.

Also, process items from the main thread.

RemoteStore: Add option to drop old connections from the pool 
This is a hack to make hydra-queue-runner free its temproots
periodically, thereby ensuring that garbage collection of the
corresponding paths is not blocked until the queue runner is
restarted.

It would be better if temproots could be released earlier than at
process exit. I started working on a RAII object returned by functions
like addToStore() that releases temproots. However, this would be a
pretty massive change so I gave up on it for now.

ThreadPool: On exception, interrupt the other worker threads 2017-09-08 15:31:24 +02:00

ThreadPool: Improve exception handling 
In particular, process() won't return as long as there are active
items. This prevents work item lambdas from referring to stack frames
that no longer exist.

nix run: Allow passing a command to execute 
E.g.

  nix run nixpkgs.hello -c hello --greeting Hallo

Note that unlike "nix-shell --command", no quoting of arguments is
necessary.

"-c" (short for "--command") cannot be combined with "--" because they
both consume all remaining arguments. But since installables shouldn't
start with a dash, this is unlikely to cause problems.

readLink(): Handle symlinks in /proc 
Symlinks like /proc/self/exe report a stat() size of 0, so use a
buffer of at least PATH_MAX instead.

Give activities a verbosity level again 
And print them (separately from the progress bar) given sufficient -v
flags.

Allow activities to be nested 
In particular, this allows more relevant activities ("substituting X")
to supersede inferior ones ("downloading X").

This allows the progress bar to display "building perl-5.22.3" instead
of "building /nix/store/<hash>-perl-5.22.3.drv".

Andy Wingo 6bb4e3e8fe Remove unused decodeOctalEscaped 
Besides being unused, this function has a bug that it will incorrectly
decode the path component Ubuntu\04016.04.2\040LTS\040amd64 as
"Ubuntu.04.2 LTS amd64" instead of "Ubuntu 16.04.2 LTS amd64".

Progress indicator: Unify "copying" and "substituting" 
They're the same thing after all.

Example:

  $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped

nix search: Add a cache 
The package list is now cached in
~/.cache/nix/package-search.json. This gives a substantial speedup to
"nix search" queries. For example (on an SSD):

First run: (no package search cache, cold page cache)

  $ time nix search blender
  Attribute name: nixpkgs.blender
  Package name: blender
  Version: 2.78c
  Description: 3D Creation/Animation/Publishing System

  real    0m6.516s

Second run: (package search cache populated)

  $ time nix search blender
  Attribute name: nixpkgs.blender
  Package name: blender
  Version: 2.78c
  Description: 3D Creation/Animation/Publishing System
