Eelco Dolstra 9747ea84b4 Remove CPU locking 
This was already accidentally disabled in ba87b08. It also no longer
appears to be beneficial, and in fact slow things down, e.g. when
evaluating a NixOS system configuration:

  elapsed time:       median =      3.8170  mean =      3.8202  stddev =      0.0195  min =      3.7894  max =      3.8600  [rejected, p=0.00000, Δ=0.36929±0.02513]

pennae 09b245690a bulk-allocate Value instances in the evaluator 
calling GC_malloc for each value is significantly more expensive than
allocating a bunch of values at once with GC_malloc_many. "a bunch" here
is a GC block size, ie 16KiB or less.

this gives a 1.5% performance boost when evaluating our nixos system.

tested with

nix eval --raw --impure --expr 'with import <nixpkgs/nixos> {}; system'

Eelco Dolstra ec8f24ed3a Ignore EPERM when unsharing FS state 
On Docker (but not podman), unshare(CLONE_FS) fails with EPERM. So
let's ignore it and hope nothing bad happens.

Attempted fix for #5777.

regnat 2eec2f765a Add a crude tracing mechansim for the build results 
Add a `_NIX_TRACE_BUILT_OUTPUTS` environment variable that can be set to
a filename in which the result of each build will be logged.

This is intentionally crude and undocumented as it’s only meant to be a
temporary thing to assess the usefulness of CA derivations.
Any other use would need a cleaner re-implementation first.

regnat 55dbb7f1cc More properly track the status of CA builds 
Make the build of unresolved derivations return the same status as the
resolved one, except in the case of an `AlreadyValid` in which case it
will return `ResolvesToAlreadyValid` to mean that the outputs of the unresolved
derivation weren’t known, but the resolved one is.

RunPager: restore stdout upon pager exit 
Before this change, stdout was closed after the pager exits. This is
fine for non-interactive commands where we want to exit right after
the pager exits anyways, but for interactive things (e.g. nix repl)
this breaks the output after we quit the pager.

Keep the initial stdout fd as part of RunPager, and restore it in
RunPager::~RunPager using dup2.
