e0204f8d46 Move path info caching from BinaryCacheStore to Store
Caching path info is generally useful. For instance, it speeds up "nix
path-info -rS /run/current-system" (i.e. showing the closure sizes of
all paths in the closure of the current system) from 5.6s to 0.15s.

This also eliminates some APIs like Store::queryDeriver() and
Store::queryReferences().

d1b0909894 BinaryCacheStore::readFile(): Return a shared_ptr to a string
This allows readFile() to indicate that a file doesn't exist, and
might eliminate some large string copying.

ab3ce1cc13 Improve SIGINT handling in multi-threaded programs
The flag remembering whether an Interrupted exception was thrown is
now thread-local. Thus, all threads will (eventually) throw
Interrupted. Previously, one thread would throw Interrupted, and then
the other threads wouldn't see that they were supposed to quit.

784ee35c80 Add "nix verify-paths" command
Unlike "nix-store --verify-path", this command verifies signatures in
addition to store path contents, is multi-threaded (especially useful
when verifying binary caches), and has a progress indicator.

Example use:

$ nix verify-paths --store https://cache.nixos.org -r $(type -p thunderbird)

c10c61449f Eliminate the "store" global variable
Also, move a few free-standing functions into StoreAPI and Derivation.

Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)

69b9d8fdbd Use DT_UNKNOWN when dirent d_type extension is not supported.
edolstra:
“…since callers of readDirectory have to handle the possibility of
 DT_UNKNOWN anyway, and we don't want to do a stat call for every
 directory entry unless it's really needed.”
