do not consider thread-local allocations read-only

They are not in read-only memory the way regular `static`s are.

implement strerror_r

This isn't perfect; we end up using [this match](72a25d05bf/library/std/src/io/error.rs (L380)) rather than the platform-specific messages, but at least we show something -- this is mostly informational anyway.

port Miri to edition 2021

`cargo fix --edition` didn't change anything for either of these crates, so this looks like a very simple port. And then we can remove a bunch of annoying imports. :)

I thought this also unlocks the named format string stuff, but it seems that works on all editions except for that problem around `panic!`. Whatever. ;)

f3a98563df Auto merge of #2058 - RalfJung:variadic, r=RalfJung 
For variadic functions, accept arbitrary trailing arguments

However, make sure that if we use argument N we check the size of all arguments before that, because otherwise this might not work properly depending on how varargs are implemented. This caught bugs in our futex tests. ;)

I couldn't find a good way to systematically ensure this, so it is just something we have to be on the look for during review. (This generally applies also for fixed-arg shims: we should check the size of each parameter.)

Also treat prctl like a variadic function, Cc `@saethlin.`

0e2def5c12 Auto merge of #2054 - m-ou-se:futex-wait-bitset, r=RalfJung 
Add support for FUTEX_{WAIT,WAKE}_BITSET

FUTEX_WAIT_BITSET and FUTEX_WAKE_BITSET are extensions of FUTEX_WAIT and FUTEX_WAKE that allow tagging each waiting thread with up to 32 'labels', and then only wake up threads that match certain labels. The non-bitset operations behave like their bitset was fully set (u32::MAX), meaning that they'll wait for anything, and wake up anything.

The only other difference is that FUTEX_WAIT_BITSET uses an absolute timeout instead of an relative timeout like FUTEX_WAIT.

Often, FUTEX_WAIT_BITSET is used not for its bitset functionality, but only for its absolute timeout functionality. It is then used with a bitset of u32::MAX.

~~This adds support for only that use case to Miri, as that's all `std` currently needs. Any other bitset is still unsupported.~~

Update: This adds full support for both these syscalls.
