55c63c9b89 Remove InputScheme::fetchToStore() 
InputSchemes now only have a getAccessor(). They could be implemented
internally by fetching the input to the store, but in that case they
will just return a FSInputAccessor.

1af5d798a4 libstore/globals.cc: Automatically set cores based on cgroup CPU limit 
By default, Nix sets the "cores" setting to the number of CPUs which are
physically present on the machine. If cgroups are used to limit the CPU
and memory consumption of a large Nix build, the OOM killer may be
invoked.

For example, consider a GitLab CI pipeline which builds a large software
package. The GitLab runner spawns a container whose CPU is limited to 4
cores and whose memory is limited to 16 GiB. If the underlying machine
has 64 cores, Nix will invoke the build with -j64. In many cases, that
level of parallelism will invoke the OOM killer and the build will
completely fail.

This change sets the default value of "cores" to be
ceil(cpu_quota / cpu_period), with a fallback to
std:🧵:hardware_concurrency() if cgroups v2 is not detected.

c8c6203c2c local-derivation-goal.cc: detect unprivileged_userns_clone failure mode 
The workaround for "Some distros patch Linux" mentioned in
local-derivation-goal.cc will not help in the `--option
sandbox-fallback false` case.  To provide the user more helpful
guidance on how to get the sandbox working, let's check to see if the
`/proc` node created by the aforementioned patch is present and
configured in a way that will cause us problems.  If so, give the user
a suggestion for how to troubleshoot the problem.

6fc56318bf local-derivation-goal.cc: add comment re: CLONE_NEWUSER 
local-derivation-goal.cc contains a comment stating that "Some distros
patch Linux to not allow unprivileged user namespaces."  Let's give a
pointer to a common version of this patch for those who want more
details about this failure mode.
