When setting maximum atom table size using +t option, there will be a
integer overflow for a large size.
$ erl +t2147482625
ll_alloc: Cannot allocate 18446744073692774400 bytes of memory
(of type "atom_tab").
The overflow is caused by the arithmetic operations on int type.
When 2147482625 + 1024 it will become -2147483647 due to the signed
integerger overflow. Then the result will be resized to Uint type, which
is a unsigned long type, the negative int will first be expand to 64
bits long via sign extension, then change to unsigned type, which
becomes 18446744073692774400.
The fix is done by convert `limit` to Uint type before doing any
arithmetic operation. This will expand variable to 64 bits long type via
zero extension, then the following operation are all positive, therefore
no overflow will happen.
Note: here we assume the int `limit` passed in is always positive. If
some future change cause the `limit` passed in maybe negative, then the
current fix will also cause overflow.

Do check before we free heap fragments.

Retrying close(2) on anything other than HP-UX is likely to close
something entirely different. POSIX says that the state of the file
descriptor is unspecified, and Linux/BSD guarantee that it's closed
on return.

Fix formatting in hipe_bifs:show_pcb/1, hipe_bifs:show_estack/1,
and hipe_bifs:show_nstack/1.
fflush(stdout) before switching from printf() to erts_printf() to
avoid garbled output.
Adjust field lengths to work on both 64- and 32-bit systems.
Tested on Linux/x86_64 (64-bit) and Linux/ARMv7 (32-bit).

1.2.11 started bailing when avail_out==0 regardless of whether
there's anything to flush or not, and there's no point in adapting
the old method since it was vulnerable to bugs in other zlib
versions which updated the deflate parameters even on failure.
The api_deflateParams test has been expanded accordingly, and two
white-box cases in zip_usage has been updated to make fewer
assumptions about the output; the validity of the compressed data
is what matters, not whether it's exactly the same as the test
vector.

The lack of this caused serious data corruption when a binary was
altered after entering the queue. This went unnoticed because it
was never used without erlang:iolist_to_iovec, which always
emasculates binaries.

When the code switches from printf() to erts_printf() the output

Fixed formatting of the "H E A P" banner for 64-bit systems.

Fix for x86_64 only.
The calling native code can not handle a GC
as it has a raw pointer where to write the binary data.
If a GC happens the data (utf32) will be written
to the old deallocated heap.

This commit also adds a check to see that all files that
are part of an xi:include also have part of XML_FILES
and vice versa. It also fixes any applications where this
was not true.

Native code does not register its literals in the code header for the
loaded code. Therefore, a literal created by native code can not be
found by mark_literal(). Ignore literals that can't be found instead
of crashing (the crasdump_viewer will report such literals as
incomplete heap data, but will not crash).
