Use decode_base64() from uuencode.c when uudecode/base64 applets are included.
That function is bigger than httpd's decodeBase64(), so we use the old one when
those applets are disabled. Bloat-o-meter when one of those is enabled:

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.

Upstream commit:
Date: Tue, 2 Jun 2020 23:46:48 +1000
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.
Fixes: 6c691b3e5099 ("jobs: Only clear gotsigchld when waiting...")

Upstream commit:
Date: Fri, 10 Apr 2020 21:03:09 +1000
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.

PLATFORM_LINUX is a hidden configuration option which is disabled by
default and enabled at over a hundred locations for features that are
deemed to be Linux specific.
The only effect of PLATFORM_LINUX is to control compilation of
libbb/match_fstype.c. This file is only needed by mount and umount.
Remove all references to PLATFORM_LINUX and compile match_fstype.c
if mount or umount is enabled.

device-tree) until the first '\0' character:
IFS= read -r -d '' VARIABLE < file
In busybox ash the -d extension is also implemented, but checking the
read character for '\0' has to be performed after comparing with the
delimiter.

Some editors (like vim) use renaming strategy to save file. That means
they save a file to some random name and then rename it to final
location. The advantage is that such save is atomic.
However, crontab -e holds open fd to the temporary file, meaning it
never sees the changes. The temporary file needs to be re-opened after
the editor terminates for the changes to properly save.
