This commit adds `anyhow` as a dependency and switches over to it from
Box<dyn Error>.
It actually looks like I've kept all of my errors rather shallow, such
that we don't get a huge benefit from anyhow at present. But now that
anyhow is in use, I expect to use its "context" feature more going
forward.
I originally did not put PathPrinter into grep-printer because I
considered it somewhat extraneous to what a "grep" program does, and
also that its implementation was rather simple. But now with hyperlink
support, its implementation has grown a smidge more complicated. And
more importantly, its existence required exposing a lot more of the
hyperlink guts. Without it, we can keep things like HyperlinkPath and
HyperlinkSpan completely private.
We can now also keep `PrinterPath` completely private as well. And this
is a breaking change.
Previously, sorting worked by sorting the parents and then sorting the
children within each parent. This was done during traversal, but it only
works when sorting parents preserves the overall order. This generally
only works for '--sort path' in ascending order.
This commit fixes the rest of the sorting behavior by collecting all of
the paths to search and then sorting them before searching. We only
collect all of the paths when sorting was requested.

Adds a new eprintln_locked macro which locks STDOUT before logging
to STDERR. This patch also replaces instances of eprintln with
eprintln_locked to avoid interleaving lines.

This was once part of ripgrep, but at some point, was unintentionally
removed. The value of this warning is that since ripgrep tries to be
"smart" by default, it can be surprising if it doesn't search certain
things. This warning covers the case when ripgrep searches *nothing*,
which happens somewhat more frequently than you might expect. e.g., If
you're searching within an ignore directory.
Note that for now, we only print this message when the user has not
supplied any explicit paths. It's not clear that we want to print this
otherwise, and in particular, it seems that the message shows up too
eagerly. e.g., 'rg foo does-not-exist' will both print an error about
'does-not-exist' not existing, *and* the message about no files being
searched, which seems annoying in this case. We can always refine this
logic later.

The top-level listing was just getting a bit too long for my taste. So
put all of the code in one directory and shrink the large top-level mess
to a small top-level mess.
NOTE: This commit only contains renames. The subsequent commit will
actually make ripgrep build again. We do it this way with the naive hope
that this will make it easier for git history to track the renames.
Sigh.
