The socket receive buffer turned out to be too small for real world
systems. Use the same size as udevd to be on the safe side. As this is
just a limit and the memory is not allocated by the kernel until really
needed there is actually no memory wasted.

As soon as the socket is bound it will receive messages. Make sure the
recieve buffer size is increased before the first message is received.

/bin/login updates the preliminary UTMP record created by /bin/getty for
$LOGNAME. However, if the PID of login is not the same as getty, then
it will create a new entry. This causes GLIBC getlogin(3) to return the
string 'LOGIN' (set by getty) instead of $LOGNAME. This affects tools
like /usr/bin/logname but also various 3rd party PAM applications.

Starting with linux kernel v5.4 squashfs has a more strict parameter
checking implemented. Unlike util-linux mount, busybox never supported
the sizelimit option but simply forwards it to the kernel.
Since v5.4 mounting will fail with
squashfs: Unknown parameter 'sizelimit'
Support the sizelimit parameter by setting it in the LOOP_SET_STATUS64
structure before handing it to the kernel.
While at it also add support for the offset option, which currently will
always be set to 0.

jobs: Fix waitcmd busy loop
We need to clear gotsigchld in waitproc because it is used as
a loop conditional for the waitcmd case. Without it waitcmd
may busy loop after a SIGCHLD.
This patch also changes gotsigchld into a volatile sig_atomic_t
to prevent compilers from optimising its accesses away.

jobs: Fix infinite loop in waitproc
After we changed the resetting of gotsigchld so that it is only
done if jp is NULL, we can now get an infinite loop in waitproc
if gotsigchld is set but there is no outstanding child because
everything had been waited for previously without gotsigchld being
zeroed.
This patch fixes it by always zeroing gotsigchld as we did before.
The bug that the previous patch was trying to fix is now resolved
by switching the blocking mode to DOWAIT_NORMAL after the specified
job has been completed so that we really do wait for all outstanding
dead children.

If server responds with ETag then next time client can resend it via If-None-Match header.
Then httpd will check if file wasn't modified and if not return 304 Not Modified status code.
The ETag value is constructed from file's last modification date in unix epoch and it's size:
"hex(last_mod)-hex(file_size)" e.g. "5e132e20-417" (with quotes).
That means that it's not completely reliable as hash functions but fair enough.
The same form of ETag is used by Nginx so load balancing of static content is safe.

The Last-Modified header is used for caching.
The client (browser) will send back the received date to server via If-Modified-Since request header.
But both headers MUST be an RFC 1123 formatted string.
And the formatting consumes resources on request parsing and response generation.
Instead we can use ETag header.
This simplifies logic and the only downside is that in JavaScript the document.lastModified will return null.

RFC 2616 sec. 14.18 says that server MUST send Date header.
But in fact the header make sense only for Cache-Control and can be omitted.
In the same time the Date eats power, CPU and network resources which are critical for embedded systems.
