79457a8ad1 jemalloc: pick from upstream: Fix GCC-9.1 warning with macro GET_ARG_NUMERIC
Pick 2d6d099fed05b1509e81e54458516528bfbbf38d from upstream jemalloc:

    Fix GCC-9.1 warning with macro GET_ARG_NUMERIC

    GCC-9.1 reports following error when trying to compile file
    src/malloc_io.c and with CFLAGS='-Werror' :

    src/malloc_io.c: In function ‘malloc_vsnprintf’:
    src/malloc_io.c:369:2: error: case label value exceeds maximum value for type [-Werror]
      369 |  case '?' | 0x80:      \
          |  ^~~~
    src/malloc_io.c:581:5: note: in expansion of macro ‘GET_ARG_NUMERIC’
      581 |     GET_ARG_NUMERIC(val, 'p');
          |     ^~~~~~~~~~~~~~~
    ...
    <snip>
    cc1: all warnings being treated as errors
    make: *** [Makefile:388: src/malloc_io.sym.o] Error 1

    The warning is reported as by default the type 'char' is 'signed char'
    and or-ing 0x80 will turn the case label char negative which will be
    beyond the printable ascii range (0 - 127).

    The patch fixes this by explicitly casting the 'len' variable as
    unsigned char' inside the 'switch' statement so that value of
    expression " '?' | 0x80 " falls within the legal values of the
    variable 'len'.

d5aef6d6ca Pick 57553c3b1a5592dc4c03f3c6831d9b794e523865 from upstream:
Avoid touching all pages in extent_recycle for debug build.

    We may have a large number of pages with *zero set (since they are populated on
    demand).  Only check the first page to avoid paging in all of them.

This makes it easy to compare performance with and without 'retain:true'.

086165ecb5 Pick 50b473c8839f5408df179bdf6f2b3fd2cf5c3b2f from upstream:
Set commit properly for FreeBSD w/ overcommit.

    When overcommit is enabled, commit needs to be set when doing mmap().  The
    regression was introduced in f80c97e.

This fixes 'retain:true'.

0c885e274a Pick f80c97e477d1b3fe7778c65d9439d673738b4131 from upstream:
Rework the way jemalloc uses mmap(2) on FreeBSD.

    This makes it directly use MAP_EXCL and MAP_ALIGNED() instead
    of weird workarounds involving mapping at random places and then
    unmapping parts of them.

bff19560ee Pick 676cdd66792ccb629a978837ea2a066d5db342cc from upstream:
Disable runtime detection of lazy purging support on FreeBSD.

    The check doesn't seem to serve any purpose here, and this shaves
    off three syscalls on binary startup.

c2a2eeff5c Account for the fact that jemalloc 5.0.0 dropped STATIC_PAGE_SHIFT
in favor for using LG_PAGE directly and, thus, for the fact that
host and target don't necessarily use pages of the same sizes.

cc718496a9 After jemalloc was updated to version 5.0.0 in r319971, i386 executables
linked with AddressSanitizer (even those linked on earlier versions of
FreeBSD, or with external versions of clang) started failing with errors
similar to:

  ==14688==AddressSanitizer CHECK failed:
  /usr/src/contrib/compiler-rt/lib/asan/asan_poisoning.cc:36
  "((AddrIsAlignedByGranularity(addr))) != (0)" (0x0, 0x0)

This is because AddressSanitizer expects all the TLS data in the program
to be aligned to at least 8 bytes.

Before the jemalloc 5.0.0 update, all the TLS data in the i386 version
of libc.so added up to 80 bytes (a multiple of 8), but 5.0.0 made this
grow to 2404 bytes (not a multiple of 8).  This is due to added caching
data in jemalloc's internal struct tsd_s.

To fix AddressSanitizer, ensure this struct is aligned to at least 16
bytes, which can be done unconditionally for all architectures.  (An
earlier version of the fix aligned the struct to 8 bytes, but only for
ILP32 architectures.  This was deemed unnecessarily complicated.)

20100e740e Pick 'Remove external linkage for spin_adaptive' from upstream jemalloc
Apply the changes from upstream jemalloc 048c6679.  This is actually not
quite a cherry pick due to makefile difference and because FreeBSD does
not carry the msvc project files which were also modified in that
commit.

ca20f8ec29 o Replace __riscv__ with __riscv
o Replace __riscv64 with (__riscv && __riscv_xlen == 64)

This is required to support new GCC 7.1 compiler.
This is compatible with current GCC 6.1 compiler.

RISC-V is extensible ISA and the idea here is to have built-in define
per each extension, so together with __riscv we will have some subset
of these as well (depending on -march string passed to compiler):

__riscv_compressed
__riscv_atomic
__riscv_mul
__riscv_div
__riscv_muldiv
__riscv_fdiv
__riscv_fsqrt
__riscv_float_abi_soft
__riscv_float_abi_single
__riscv_float_abi_double
__riscv_cmodel_medlow
__riscv_cmodel_medany
__riscv_cmodel_pic
__riscv_xlen

8495e8b1e9 Fix known issues which blow up the process after dlopen("libthr.so")
(or loading a dso linked to libthr.so into process which was not
linked against threading library).

- Remove libthr interposers of the libc functions, including
  __error(). Instead, functions calls are indirected through the
  interposing table, similar to how pthread stubs in libc are already
  done.  Libc by default points either to syscall trampolines or to
  existing libc implementations.  On libthr load, libthr rewrites the
  pointers to the cancellable implementations already in libthr.  The
  interposition table is separate from pthreads stubs indirection
  table to not pull pthreads stubs into static binaries.

- Postpone the malloc(3) internal mutexes initialization until libthr
  is loaded.  This avoids recursion between calloc(3) and static
  pthread_mutex_t initialization.

- Reinstall signal handlers with wrapper on libthr load.  The
  _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2)
  when libthr is statically referenced from the main binary.

In the process, fix openat(2), swapcontext(2) and setcontext(2)
interposing.  The libc symbols were exported at different versions
than libthr interposers.  Export both libc and libthr versions from
libc now, with default set to the higher version from libthr.

Remove unused and disconnected swapcontext(3) userspace implementation
from libc/gen.
