Optionally re-introduce bb_info_msg()
Between Busybox 1.24.2 and 1.25.0 the bb_info_msg() function was
eliminated and calls to it changed to be bb_error_msg(). The downside of
this is that daemons now log all messages to syslog at the LOG_ERR level
which makes it hard to filter errors from informational messages.
This change optionally re-introduces bb_info_msg(), controlled by a new
option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that
were removed (only in applets that set logmode to LOGMODE_SYSLOG or
LOGMODE_BOTH), and also changes informational messages in ifplugd and
ntpd.
The code size change of this is as follows (using 'defconfig' on x86_64
with gcc 7.3.0-27ubuntu1~18.04)

vi: fix changes to word at end of line. Closes 11796
As reported in bug 11796 BusyBox vi incorrectly handles changes
to a word at the end of a line. If the following line starts
with whitespace changing or deleting the last word of a line
with the 'cw' or 'dw' commands causes the lines to be joined.
This happens because the range for the change returned by
find_range() covers all whitespace after the word, including
newlines. The problem can be fixed by setting 'ml' to zero
to indicate to yank_delete() that processing should stop at
the end of the current line.
However, this results in a new problem. 'dw' correctly deletes
all whitespace following the word but so does 'cw', which should
preserve the trailing whitespace. To fix this the code to omit
whitespace from the change is modified to include all whitespace
not just blanks.

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).
