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.

Daniel Poelzleithner b712d4674b Allow multiple search experssions in nix search
The common use case is to search for packages containing multiple words
like a "git" "frontend". Having only one expressions makes this simple regular
use case very complicated. Instead, search accepts multiple regular epressions
which all need to match.

nix search git 'gui|frontend'

returns a list of all git uis for example

Will Dietz 009cf9cd23 nix search: explicitly handle empty search string, fixes #1893
This is important since this is given as an example.
Other patterns containing "empty search string" will still
be handled differently on different platforms ("asdf|")
but that's less of an issue.

Will Dietz 3cac8734ac nix search: fix bug where we wrote to cache when shouldn't, breaking
This is exposed by the tests added previously,
and resolves the error reported in #1892:
"expected JSON value".

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

  real    0m0.143s

nix search: Ignore top-level eval errors
$NIX_PATH may contain elements that don't evaluate to an attrset (like
"nixos-config"), so ignore those.
