Joseph Myers 77261698b4 Implement C23 rsqrt 
C23 adds various <math.h> function families originally defined in TS
18661-4.  Add the rsqrt functions (1/sqrt(x)).  The test inputs are
taken from those for sqrt.

Tested for x86_64 and x86, and with build-many-glibcs.py.

Samuel Thibault 81c4ec1ca8 htl: Make __pthread_sigmask directly call __sigthreadmask 
If no thread was created yet, __pthread_sigstate will not find our ss
because self->kernel_thread is still nul, and then change the global
sigstate instead of our sigstate! We can directly call __sigthreadmask and
skip the (bogus) lookup step.

Adhemerval Zanella 1d60b9dfda Remove dl-procinfo.h 
powerpc was the only architecture with arch-specific hooks for
LD_SHOW_AUXV, and with the information moved to ld diagnostics there
is no need to keep the _dl_procinfo hook.

Checked with a build for all affected ABIs.

Samuel Thibault cf13f740a9 bits/socket.h: Update to recent BSD definition 
The old BSD 4.4 definition (not used by Linux) was not 64b-proof: the
cmsg_data field is supposed to CMSG_ALIGN'ed (as can be also seen in the
CMSG_LEN macro).

Adhemerval Zanella 0ca8785a28 elf: Do not change stack permission on dlopen/dlmopen 
If some shared library loaded with dlopen/dlmopen requires an executable
stack, either implicitly because of a missing GNU_STACK ELF header
(where the ABI default flags implies in the executable bit) or explicitly
because of the executable bit from GNU_STACK; the loader will try to set
the both the main thread and all thread stacks (from the pthread cache)
as executable.

Besides the issue where any __nptl_change_stack_perm failure does not
undo the previous executable transition (meaning that if the library
fails to load, there can be thread stacks with executable stacks), this
behavior was used on a CVE [1] as a vector for RCE.

This patch changes that if a shared library requires an executable
stack, and the current stack is not executable, dlopen fails.  The
change is done only for dynamically loaded modules, if the program
or any dependency requires an executable stack, the loader will still
change the main thread before program execution and any thread created
with default stack configuration.
