musl: update musl to 1.1.16+ and switch to download from git

This patch updates musl to 1.1.16+ [0] and removes all the
backported patches. This is a major release and tagged as such.
For more information visit musl-libc.org or read the WHATSNEW.

Furthermore, this patch also changes musl to download directly
from git. This makes it easier to update musl in the future.

The patch custom Add-format-attribute-to-some-function-declarations.patch
was assigned a new 400- number. This should avoid confusion
since 0xx numbers are usually assigned to backports.

-Subject: fix pread/pwrite syscall calling convention on sh
-
-despite sh not generally using register-pair alignment for 64-bit
-syscall arguments, there are arch-specific versions of the syscall
-entry points for pread and pwrite which include a dummy argument for
-alignment before the 64-bit offset argument.

-
-commit b91cdbe2bc8b626aa04dc6e3e84345accf34e4b1, in fixing another
-issue, changed the logic for how alt-form octal adds the leading zero
-to adjust the precision rather than using a prefix character. this
-wrongly suppressed the zero flag by mimicing an explicit precision
-given by the format string. switch back to using a prefix character.
-
-based on bug report and patch by Dmitry V. Levin, but simplified.

-Subject: fix undefined behavior in sched.h cpu_set_t usage
-
-since cpu sets can be dynamically allocated and have variable size,
-accessing their contents via ->__bits is not valid; performing pointer
-arithmetic outside the range of the size of the declared __bits array
-results in undefined beahavior. instead, only use cpu_set_t for
-fixed-size cpu set objects (instantiated by the caller) and as an
-abstract pointer type for dynamically allocated ones. perform all
-accesses simply by casting the abstract pointer type cpuset_t * back
-to unsigned long *.

-Subject: fix missing integer overflow checks in regexec buffer size
- computations
-
-most of the possible overflows were already ruled out in practice by
-regcomp having already succeeded performing larger allocations.
-however at least the num_states*num_tags multiplication can clearly
-overflow in practice. for safety, check them all, and use the proper
-type, size_t, rather than int.
-
-also improve comments, use calloc in place of malloc+memset, and
-remove bogus casts.

-Subject: fix regexec with haystack strings longer than INT_MAX
-
-we inherited from TRE regexec code that's utterly wrong with respect
-to the integer types it's using. while it doesn't appear that
-compilers are producing unsafe output, signed integer overflows seem
-to happen, and regexec fails to find matches past offset INT_MAX.
-
-this patch fixes the type of all variables/fields used to store
-offsets in the string from int to regoff_t. after the changes, basic
-testing showed that regexec can now find matches past 2GB (INT_MAX)
-and past 4GB on x86_64, and code generation is unchanged on i386.

-Subject: fix integer overflow in float printf needed-precision computation
-
-if the requested precision is close to INT_MAX, adding
-LDBL_MANT_DIG/3+8 overflows. in practice the resulting undefined
-behavior manifests as a large negative result, which is then used to
-compute the new end pointer (z) with a wildly out-of-bounds value
-(more overflow, more undefined behavior). the end result is at least
-incorrect output and character count (return value); worse things do
-not seem to happen, but detailed analysis has not been done.
-
-this patch fixes the overflow by performing the intermediate
-computation as unsigned; after division by 9, the final result
-necessarily fits in int.

-Subject: fix integer overflows and uncaught EOVERFLOW in printf core
-
-this patch fixes a large number of missed internal signed-overflow
-checks and errors in determining when the return value (output length)
-would exceed INT_MAX, which should result in EOVERFLOW. some of the
-issues fixed were reported by Alexander Cherepanov; others were found
-in subsequent review of the code.
-
-aside from the signed overflows being undefined behavior, the
-following specific bugs were found to exist in practice:
-
-- overflows computing length of floating point formats with huge
-  explicit precisions, integer formats with prefix characters and huge
-  explicit precisions, or string arguments or format strings longer
-  than INT_MAX, resulted in wrong return value and wrong %n results.
-
-- literal width and precision values outside the range of int were
-  misinterpreted, yielding wrong behavior in at least one well-defined
-  case: string formats with precision greater than INT_MAX were
-  sometimes truncated.
-
-- in cases where EOVERFLOW is produced, incorrect values could be
-  written for %n specifiers past the point of exceeding INT_MAX.
-
-in addition to fixing these bugs, we now stop producing output
-immediately when output length would exceed INT_MAX, rather than
-continuing and returning an error only at the end.

-
-j is int32_t and thus j<<31 is undefined if j==1, so j is changed to
-uint32_t locally as a quick fix, the generated code is not affected.
-
-(this is a strict conformance fix, future c standard may allow 1<<31,
-see DR 463.  the bug was inherited from freebsd fdlibm, the proper fix
-is to use uint32_t for all bit hacks, but that requires more intrusive
-changes.)

-posix requires that EINVAL be returned if the first parameter specifies
-the cpu-time clock of the calling thread (CLOCK_THREAD_CPUTIME_ID).
-linux returns ENOTSUP instead so we handle this.

-
-in nearest rounding mode exact halfway cases were not following the
-round to even rule if the rounding happened at a base 1000000000 digit
-boundary of the internal representation and the previous digit was odd.

-Subject: fix strtod and strtof rounding with many trailing zeros
-
-in certain cases excessive trailing zeros could cause incorrect
-rounding from long double to double or float in decfloat.
-
-e.g. in strtof("9444733528689243848704.000000", 0) the argument
-is 0x1.000001p+73, exactly halfway between two representible floats,
-this incorrectly got rounded to 0x1.000002p+73 instead of 0x1p+73,
-but with less trailing 0 the rounding was fine.
-
-the fix makes sure that the z index always points one past the last
-non-zero digit in the base 10^9 representation, this way trailing
-zeros don't affect the rounding logic.

-Subject: fix strtod int optimization in non-nearest rounding mode
-
-the mid-sized integer optimization relies on lnz set up properly
-to mark the last non-zero decimal digit, but this was not done
-if the non-zero digit lied outside the KMAX digits of the base
-10^9 number representation.
-
-so if the fractional part was a very long list of zeros (>2048*9 on
-x86) followed by non-zero digits then the integer optimization could
-kick in discarding the tiny non-zero fraction which can mean wrong
-result on non-nearest rounding mode.
-
-strtof, strtod and strtold were all affected.

-Subject: fix build regression on archs with variable page size
-
-commit 31fb174dd295e50f7c5cf18d31fcfd5fe5a063b7 used
-DEFAULT_GUARD_SIZE from pthread_impl.h in a static initializer,
-breaking build on archs where its definition, PAGE_SIZE, is not a
-constant. instead, just define DEFAULT_GUARD_SIZE as 4096, the minimal
-page size on any arch we support. pthread_create rounds up to whole
-pages anyway, so defining it to 1 would also work, but a moderately
-meaningful value is nicer to programs that use
-pthread_attr_getguardsize on default-initialized attribute objects.
