nix copy: Make -r option use the "from" store 
Previously, we tried to compute the closure in the local store, which
obviously doesn't work.

copyPaths(): Use queryValidPaths() to reduce SSH latency 2017-03-16 13:50:01 +01:00

copyPaths(): Don't query path info for a path the target already has 
For example, this cuts "nix-copy-closure --from" on a NixOS system
closure from 15.9s to 0.5s.

LegacySSHStore: Provide a faster implementation of computeFSClosure() 
This avoids the latency of the standard implementation, which can make
a huge difference (e.g. 16.5s -> 0.5s on a NixOS system closure).

runProgram(): Distinguish between empty input and no input 
For example, if we call brotli with an empty input, it shouldn't read
from the caller's stdin.

Compress NAR listings using the "text-compression" method 
So if "text-compression=br", the .ls file in S3 will get a
Content-Encoding of "br". Brotli appears to compress better than xz
for this kind of file and is natively supported by browsers.

S3BinaryCacheStore: Support compression of narinfo and log files 
You can now set the store parameter "text-compression=br" to compress
textual files in the binary cache (i.e. narinfo and logs) using
Brotli. This sets the Content-Encoding header; the extension of
compressed files is unchanged.

You can separately specify the compression of log files using
"log-compression=br". This is useful when you don't want to compress
narinfo files for backward compatibility.

Add support for brotli compression 
Build logs on cache.nixos.org are compressed using Brotli (since this
allows them to be decompressed automatically by Chrome and Firefox),
so it's handy if "nix log" can decompress them.

BinaryCacheStore: Implement getBuildLog() 
We assume that build logs are stored under log/<drv>, e.g.

  /nix/store/q7ab198v13p0f8x8wgnd75dva7d5mip6-friday-devil-0.1.1.1.drv

maps to

  https://cache.nixos.org/log/q7ab198v13p0f8x8wgnd75dva7d5mip6-friday-devil-0.1.1.1.drv

Add a "nix log" command 
This replaces "nix-store --read-log". It checks the local store and
any configured substituters for the requested logs.

Store: Add a method for getting build logs 
This allows various Store implementations to provide different ways to
get build logs. For example, BinaryCacheStore can get the build logs
from the binary cache.

Also, remove the log-servers option since we can use substituters for
this.

Improve SSH handling 
* Unify SSH code in SSHStore and LegacySSHStore.

* Fix a race starting the SSH master. We now wait synchronously for
  the SSH master to finish starting. This prevents the SSH clients
  from starting their own connections.

* Don't use a master if max-connections == 1.

* Add a "max-connections" store parameter.

* Add a "compress" store parameter.

TeeSink: Pre-reserve string space 
When receiving a very large file, this can prevent the string from
having tobe copied, which temporarily doubles memory consumption.

readString(): Read directly into std::string 
When reading a huge string, this halves memory consumption.

(Strictly speaking, this appears only valid in C++17, but who cares...)
