ad16f89547 httpd: if no request was given at all, close the socket without generating error page
For one, an attacker can try to overload us by just opening and immediately
closing tons of connections - reduce our work to the minimum for this case.

4864a68596 httpd: Support caching via ETag header
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.

b6efac31d8 httpd: Don't add Last-Modified header to response
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.

17764603f2 httpd: allow '-h' to work when daemonized with NOMMU enabled
Commit d1b75e184 (httpd: permit non-default home directory with NOMMU
enabled) only works when used with the '-f' (foreground) option.

When '-f' isn't specified and NOMMU is enabled bb_daemonize_or_rexec()
is called to daemonize the server.  Since the server process has been
re-execed the previous patch results in the xchdir() not being called.

Fix this by resetting the re_execed variable in this case.

d1b75e1842 httpd: permit non-default home directory with NOMMU enabled
When BusyBox is compiled with NOMMU enabled running httpd with
the '-h' option fails even if the specified directory exists:

   $ ls -d www
   www
   $ busybox httpd  -fvvvp 8080 -h www
   ...
   ... try to access http://localhost:8080/www
   ...
   httpd: can't change directory to 'www': No such file or directory

The parent process executes xchdir("www").  When a connection is accepted
it's handled by re-executing httpd in inetd mode.  The child process
inherits the current directory "www" and tries to change directory again
to "www", which fails.

Omit the call to xchdir() when httpd is re-executed.

6937487be7 libbb: reduce the overhead of single parameter bb_error_msg() calls
Back in 2007, commit 0c97c9d437 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().

This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.

Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.

This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.

The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):

Arm:     -92 bytes
MIPS:    -52 bytes
PPC:   -1836 bytes
x86_64: -938 bytes

Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.

bae8f7eaf2 httpd: do not percent-decode URI if proxying
The proxying is documented as follows:

P:/url:[http://]hostname[:port]/new/path

Howeverm urlcopy is not a true copy anymore when it is fdprint'ed
to proxy_fd, this is because percent_decode_in_place() is called
after the copy is created.

This breaks reverse proxying all URIs containing percent
encoded spaces, e.g. - because a decoded URI will be printed out
to proxy_fd instead of the original.

The fix keeps the logic in place to canonicalize the uri first,
before reverse proxying (one could argue that the uri
should be proxied completely unaltered, except for the prefix
rewrite).
