setting this only on exceptions caused by actual fd access is not
sufficient to diagnose all errors (such as SerialisationError) in
some cases. this usually does not have any negative effects since
those errors will end up killing the process in another way. this
is not a reliable assumption though and we should be using proper
error handling (and closing connections more often, preferring to
close over keeping something open that might be in a weird state)

not needed yet, but returning a resource from the exception handling
path that has ownership of a handle is currently not well-supported.
we could also add a default constructor to Handle, but then we would
also need to change the pool reference to a pointer. eventually that
should be done since now resources can be swapped between pools with
clever moves, but since that's not a problem yet we won't do it now.

the duplication of exception handling was added without justification,
so we can only assume that it was done like this because Finally could
not throw exceptions safely. since this has now been rectified we will
deduplicate this handler code again.

this is supposed to act like a finally block does in other languages. a
finally block should be able to throw exceptions of its own rather than
just crashing the entire program when it throws it own exceptions. even
in the rare case of a finally throwing an unexpected exception it might
be better to report the exception from Finally instead of the original,
at least that can keep our program running instead of letting it crash.

usage of this flag previously kept connections open much longer than
necessary, and at the same time obscured that a connection was being
dropped when it *was* set. new variable names clarify this somewhat.

it was used incorrectly (not swapped on handle move), only used in one
place (that is now handled with exception handling detection in Handle
itself), and if ever reintroduced should be replaced with a different,
more understandable mechanism (like an explicit dropAsInvalid method).
Change-Id: Ie3e5d5cfa81d335429cb2ee5c3ad85c74a9df17b
this was never actually used, and bad design in the first place—why
should a bad resource be put back into the idle pool? just drop it.
Change-Id: Idab8774bee19dadae0209d404c4fb86dd4aeba1e
if a scope owning a resource does not gracefully drop that resource
while handling exceptions from deeper down the call stack we should
assume the resource is invalid state and drop it. currently it *is*
true that such cases do not cause resources to be freed, but thanks
to validator misuses this has so far not caused any larger problem.

Perl has an env hook[1]. Passing the paths manually without putting them
in buildInputs is harder to understand, plays less nicely with dev
shells, and is less build-generic.
Produced identical output on my x86_64-linux machine, and on my
aarch64-darwin machine was identical save for the derivation output path
which gets embedded into the .dylib Mach-O.

this notably does *not* install the `nix3-manpages` manpage the old
system generated, mostly because that page was empty and just a bug
with a coat of documentation paint.

we'll want to use these for the meson builds, and probably eventually
rewrite them in something that isn't plain shell. diffoscope confirms
that out/share and doc/share are equal before and after these changes

The big ones here are `trim-trailing-whitespace` and `end-of-file-fixer`
(which makes sure that every file ends with exactly one newline
character).

This does involve making a large number of destructors able to throw,
because we had to change it high in the class hierarchy. Oh well.

This has not yet had all the warnings Obliterated, but it is a start and
is not *super* far away from being able to run the current configuration
in CI, which will catch some limited number of mistakes.
I tried the meson clang-tidy target and it seems to fail to find flags
for several files, which seems broken. Unsure what is up with that, but
we can use run-clang-tidy or other tooling instead.
We have an extremely annoying situation with the lexer table, which
means that the lexer probably must be moved to another directory with
its own .clang-tidy file to disable the lints in it, *or* write scuffed
code that prepends a disable comment to the top of the generated file.
None of the comment-based lint disabling features work since yacc dumps
a bunch of non compliant code at the top of the file before anything the
user can control.

* some things that can throw are marked noexcept
yet the linter seems to think not. Maybe they can't throw in practice.
I would rather not have the UB possibility in pretty obvious cold
paths.
* various default-case-missing complaints
* a fair pile of casts from integer to character, which are in fact
deliberate.
* an instance of <https://clang.llvm.org/extra/clang-tidy/checks/bugprone/move-forwarding-reference.html>
* bugprone-not-null-terminated-result on handing a string to curl in
chunks of bytes. our usage is fine.
* reassigning a unique_ptr by CRIMES instead of using release(), then
using release() and ignoring the result. wild. let's use release() for
its intended purpose.

We got confused what formals did and had to briefly figure it out. We

Since we don't have a ./configure checked in, it makes no sense to keep
any of these scripts since people are already going to be running
autoreconf anyway.
Plus they will be completely deletable when meson shows up.
This fixes `autoreconfPhase` causing git diffs.
Change-Id: Ibb2aee422c562a23faadfdedb55b5c18c41a9420
the autoconf build system defaults to /nix/var, not /nix/var/nix. the
latter is only used in libstore, so we'll move the extra segment there.

Without this, the Meson setup won't bail out if nlohmann_json is
missing, leading to subpar DX (and maybe worse, but I'm not entirely
sure).

one headers (args/root.hh) was simply missing, and the generated headers
were not installed. not all of them *should* be installed either, only a
select few (and sadly this needs a custom target for each one, it seems)

sometimes these fail with timeouts on loaded machines. let's up the
timeouts until we can pull the tests apart to more reasonable sizes

- Enable parallel builds by default (and allow using environment
variables to override `make` variables)
- Hopefully we can get rid of this once we have Meson
- Set `GTEST_BRIEF=1`
- This only shows failed tests, instead of listing every test on its
own line.
```
$ GTEST_BRIEF=1 make check
