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.

This is exposed by the tests added previously,
and resolves the error reported in #1892:
"expected JSON value".

Manual: Update chapter on remote builds 
Alos add a command "nix ping-store" to make it easier to see if Nix
can connect to a remote builder (e.g. 'nix ping-store --store
ssh://mac').

78ac3eb4eb Fix #1762 
nix-store --export, nix-store --dump, and nix dump-path would previously
fail silently if writing the data out failed, because
 a) FdSink::write ignored exceptions, and
 b) the commands relied on FdSink's destructor, which ignores
    exceptions, to flush the data out.

This could cause rather opaque issues with installing nixos, because
nix-store --export would happily proceed even if it couldn't write its
data out (e.g. if nix-store --import on the other side of the pipe
failed).

This commit adds tests that expose these issues in the nix-store
commands, and fixes them for all three.

Add plugins to make Nix more extensible. 
All plugins in plugin-files will be dlopened, allowing them to
statically construct instances of the various Register* types Nix
supports.

Improve filtering of ANSI escape sequences in build logs 
All ANSI sequences except color setting are now filtered out. In
particular, terminal resets (such as from NixOS VM tests) are filtered
out.

Also, fix the completely broken tab character handling.

Add 'nix upgrade-nix' command 
This command upgrades Nix to the latest stable version by installing a
store path obtained from

  https://github.com/NixOS/nixpkgs/raw/master/nixos/modules/installer/tools/nix-fallback-paths.nix

which is the same store path that the installer at
https://nixos.org/nix/install.sh uses.

The upgrade fails if Nix is not installed in a profile (e.g. on NixOS,
or when installed outside of the Nix store).
