d66d6d15f1 Use getentropy() for seeding PRNG 
The getentropy function, found on Linux, OpenBSD, and recently also
FreeBSD, can be used to get random bytes to initialize the PRNG.  It
is similar to the traditional way of reading from /dev/urandom, but
being a system call rather than a special file, it doesn't suffer from
problems like running out of file descriptors, or failure when running
in a container where /dev/urandom may not be available.

Regtested on x86_64-pc-linux-gnu, Ok for trunk?

dffb1e2279 PR 84519 Handle optional QUIET specifier for STOP and ERROR STOP 
Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP
statements, in order to suppress the printing of signaling FP
exceptions and the stop code. This patch adds the necessary library
changes, but for now the new specifier is not parsed and the frontend
unconditionally adds a false value for the new argument.

3f5fabc0ea Character length cleanup for Coarray Fortran library 
Following the change to use size_t for Fortran character lengths (PR
78534), this patch modifies the Coarray ABI in a similar way. The
single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.

variables are used as array indices allows accessing larger arrays,

4135a21f4d PR 78534 Regression on 32-bit targets 
By switching from int to size_t in order to handle larger values,
r256322 introduced a bug that manifested itself on 32-bit
targets. Fixed by using the correct type to store the result of a
next_array_record call.

Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu, committed to
trunk as obvious.

In order to handle large characters when doing formatted I/O, use
size_t and ptrdiff_t for lengths.  Compared to the previous patch,
based on discussions on IRC use size_t for sizes that don't need to be
negative rather than ptrdiff_t everywhere.

f622221ab4 PR 78534 Change character length from int to size_t 
In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.

This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.

I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.

Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.

I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.

This is v5 of the patch. v4 was applied but caused breakage on big
endian targets. These have been fixed and tested, thanks to access to
the GCC compile farm.

Overview of v4 of the patch: v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.

Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.

Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and
powerpc64-unknown-linux-gnu. Also regtested all three targets by
modifying gfortran-dg.exp to also test with "-g -flto", no new
failures observed.

2412750e79 PR libgfortran/83649 Chunk large reads and writes 
It turns out that Linux never reads or writes more than 2147479552
bytes in a single syscall. For writes this is not a problem as
libgfortran already contains a loop around write() to handle short
writes. But for reads we cannot do this, since then read will hang if
we have a short read when reading from the terminal.  Also, there are
reports that macOS fails I/O's larger than 2 GB.  Thus, to work around
these issues do large reads/writes in chunks.

The testcase from the PR

program largewr
  integer(kind=1) :: a(2_8**31+1)
  a = 0
  a(size(a, kind=8)) = 1
  open(10, file="largewr.dat", access="stream", form="unformatted")
  write (10) a
  close(10)
  a(size(a, kind=8)) = 2
  open(10, file="largewr.dat", access="stream", form="unformatted")
  read (10) a
  if (a(size(a, kind=8)) == 1) then
    print *, "All is well"
  else
    print *, "Oh no"
  end if
end program largewr

fails on trunk but works with the patch.

Regtested on x86_64-pc-linux-gnu, committed to trunk.
