Also fix and document the broken +We option.

Given some pointer *x, calling sizeof(x) will give us
the size of the pointer (4/8 bytes) not the size fo the
underlying dereferenced structure. Use coccinelle to
search for these occurrences in the source code, and
correct them one by one. In the case of
erl_node_tables.c, the erts_snprintf() calls used a
much too small buffer.
- run_erl.c: Use the size of the signal type, not
its pointer.
- erl_node_tables.c: Use the size of the _BUFFER in
erts_snprintf() to make sure we can use the full space.

If the driver queue is empty, or the user is requesting a 'read'
shutdown, then the shutdown() syscall is performed synchronously, as
per the old version of shutdown/2.
However, if the user is requesting a 'write' or 'read_write' shutdown,
and there is data in the driver queue for the socket, then the
shutdown() syscall is delayed and handled asynchronously when the
driver queue is written out.
This version of shutdown solves a number of issues with the old
version. The two main solutions it offers are:
* It doesn't block when the TCP peer is idle or slow. This is the
expected behaviour when shutdown() is called: the caller needs
to be able to continue reading from the socket, not be prevented
from doing so.
* It doesn't truncate the output. The current version of
gen_tcp:shutdown/2 will truncate any outbound data in the driver
queue after about 10 seconds if the TCP peer is idle of slow. Worse
yet, it doesn't even inform anyone that the data has been
truncated: 'ok' is returned to the caller; and a FIN rather than
an RST is sent to the TCP peer.
For a detailed description of all the problems with the old version
of shutdown, please see the EEP Light that was written to justify
this patch.

Previously, the emulator would generate a whole string
with values and call the error_logger passing "~s~n".
This commit changes it to a format string containing ~p
with the respective values as arguments.
|
|
This function allows us to send format and args to the
logger which can then be formatted and customized from
Erlang land.

There is no need to take special care of Maps at all since header_arity(hdr)
will take care of the normal case via its Map handling.

The optimization cannot be used due to that the pattern cannot be ordered.

The current size is too small for 64-bit machines,

sys_write_buf allocator type is used from async-threads and needs
to be lockable. In the SMP case the temporary allocator is lockable but
not in the Non-SMP case.
To remedy this the binary-allocator is used for the Non-SMP case,
which is lockable.

The Android support in erl_child_setup.c is broken:
1. The close fd loop compares an fd (integer i) with the address of the function
__system_properties_fd rather than the value of calling that function.
2. This function is locally defined, but its name starts with two underscores
which is reserved for the implementation.
3. This function is not used outside of this file, so should be static.
4. This function performs a fair amount of work (calls getenv and atoi), which
would be repeated for each and every fd in the [from,to] range.
5. This function contains an unsed local variable 's'.
Fixed by dropping the __ prefix, making the function static, dropping the unused
local variable, and rewriting the close fd loop to call the function at most once.

* i_minus specialization on x registers
* i_plus specialization on x registers

check (nbytes == 0 && d->c.sendfile.nbytes == 0) when efile_sendfile returns 0 and
has EAGAIN set.
FreeBSD sendfile(2) man page:
When using a socket marked for non-blocking I/O, sendfile() may send
fewer bytes than requested. In this case, the number of bytes
successfully written is returned in *sbytes (if specified), and the error
EAGAIN is returned.
The number of bytes successfully written can be 0. If this happens and
in a request handling either file:sendfile/2 or file:sendfile/5 with Bytes=0,
the sendfile loop will stop prematurely and file:sendfile will return
{ok, BytesSent} where BytesSent < DataAfterOffset, effectively breaking sendfile
support on FreeBSD.

May lessen load/store latency.
