a5dae62e85 fix(3p/nix): Use SkipEmpty in all calls to absl::StrSplit
The behavior to return a list containing a single empty string when
provided an empty string is a behavior that absl inherited from legacy
code. However, the behavior expected by legacy code in Nix is the
behavior provided by the SkipEmpty option. Switch all calls to use
SkipEmpty, except for the call already using SkipWhitespace.

See also commit 26a59482d2, with the
partly-prophetic message: "there may be other places we need to
fix this as well."

1cbffe21f3 chore(3p/nix/hash): prefer StatusOr over throwing constructor
The use of `unwrap_throw` can be used as a later grep target.

3652326ed2 refactor(3p/nix): Anchor local includes at src/
Previously all includes were anchored in one global mess of header
files. This moves the includes into filesystem "namespaces" (if you
will) for each sub-package of Nix.

Note: This commit does not introduce the relevant build system changes.

bf452cbc2a refactor(3p/nix): Replace tokenizeStrings with absl::StrSplit
This function was a custom (and inefficient in the case of
single-character delimiters) string splitter which was used all over
the codebase. Abseil provides an appropriate replacement function.

98299da0fd refactor(3p/nix/libutil): Replace string2Int & trim functions
Replaces these functions with corresponding functions from Abseil,
namely absl::StripAsciiWhitespace and absl::SimpleAtoi.

In the course of doing this some minor things I encountered along the
way were also refactored.

This also changes the signatures of the various custom readFile
functions to use absl::string_view types.

838f86b0fd style(3p/nix): Remove 'using std::*' from types.hh
It is considered bad form to use things from includes in headers, as
these directives propagate to everywhere else and can make it
confusing.

types.hh (which is includes almost literally everywhere) had some of
these directives, which this commit removes.

3908732181 style(3p/nix): Final act in the brace-wrapping saga
This last change set was generated by a full clang-tidy run (including
compilation):

    clang-tidy -p ~/projects/nix-build/ \
      -checks=-*,readability-braces-around-statements -fix src/*/*.cc

Actually running clang-tidy requires some massaging to make it play
nice with Nix + meson, I'll be adding a wrapper or something for that soon.

1841d93ccb style(3p/nix): Add braces around single-line for-loops
These were not caught by the previous clang-tidy invocation, but were
instead sorted out using amber[0] as such:
