9173c9cce4 ed: add support for -s command-line option as mandated by POSIX
Apart from the -p option, POSIX also mandates an -s option which
suppresses the output of byte counts for the e, E, r, and w command.
From these commands, Busybox ed presently only implements the r and w
commands. This commit ensures that these two command do not output any
bytes counts when the -s option is passed. The shell escape command,
also effected by the -s option, is not implemented by Busybox at the
moment.

4fe954c148 sed: do not ignore 'g' modifier when match starts with ^
It is perfectly valid to start a regex with ^ and have other patterns
with \| that can match more than once, e.g. the following example
should print ca, as illustrated with gnu sed:
$ echo 'abca' | sed -e 's/^a\|b//g'
ca

busybox before patch:
$ echo 'abca' | busybox sed -e 's/^a\|b//g'
bca

busybox after patch:
$ echo 'abca' | ./busybox sed -e 's/^a\|b//g'
ca

regcomp handles ^ perfectly well as illustrated with the second 'a' that
did not match in the example, we ca leave the non-repeating to it if
appropriate.
The check had been added before using regcomp and was required at the
time (f36635cec6) but no longer makes sense now.

(tested with glibc and musl libc)

a05a3d5932 ed: align output of read command with POSIX.1-2008
POSIX.1-2008 mandates the following regarding the read command:

	If the read is successful, and -s was not specified, the number
	of bytes read shall be written to standard output in the
	following format:

	    "%d\n", <number of bytes read>

This commit aligns the output of busybox ed with POSIX.1-2008 by
removing the file name from the output for the read command.

This slipped through in 4836a0708fd0aaeb82871a3762b40fcf4b61e812.

f26eb796e2 ed: fix current line number for file passed via the command-line
POSIX.1-2008 mandates the following regarding the file command-line
argument:

	If the file argument is given, ed shall simulate an e command
	on the file named by the pathname […]

The specification for the e command mandates the following behaviour
regarding the current line number in POSIX.1-2008:

	The current line number shall be set to the address of the last
	line of the buffer.

However, without this commit, busybox ed will set the current line
number to 1 if a file is given on the command-line and this file is not
empty (lastNum != 0). This is incorrect and fixed in this commit by not
modifying the current line number in ed_main(). As such, the current
line number will be zero for empty files and otherwise be set to the
address of the last line of the buffer.

bfd8738154 ed: add support for -p command-line option as mandated by POSIX
The POSIX.1-2008 specification of ed(1) mandates two command-line
options: -p (for specifying a prompt string) and -s (to suppress writing
of byte counts). This commit adds support for the former. Furthermore,
it also changes the default prompt string to an empty string (instead
of ": ") since this is also mandated by POSIX:

	-p string Use string as the prompt string when in command mode.
	          By default, there shall be no prompt string.

7105e4afdd printf: allow 0 as a flag and allow multiple flags
The '%' character in a format specification may be followed by
one or more flags from the list "+- #0".  BusyBox printf didn't
support the '0' flag or allow multiple flags to be provided.
As a result the formats '%0*d' and '%0 d' were considered to be
invalid.

The lack of support for '0' was pointed out by Andrew Snyder on the
musl mailing list:

cb91a818c8 libarchive/get_header_ar.c: fix extraction of archives from binutils in deterministic mode
GNU binutils in deterministic mode (ar rD or built with
--enable-deterministic-archives) hard codes file mode to 0644 (NOT 0100644)
since https://github.com/bminor/binutils-gdb/commit/36e4dce69dd2

This confuses busybox ar x (data_extract_all):

touch a; ar rD a.ar a
ar: creating a.ar

busybox ar x a.ar
ar: unrecognized file type
hexdump -C a.ar

As a workaround, force the mode bits to S_IFREG, as nothing else makes sense
for ar.

e67b80f473 udhcpc6: fix udhcp_find_option to actually find DHCP6 options
udhcp_insert_new_option treats code for IPv6 as follows:

new->data[D6_OPT_CODE] = code >> 8;
new->data[D6_OPT_CODE + 1] = code & 0xff;

udhcp_find_option tests the code as follows:

while (opt_list && opt_list->data[OPT_CODE] < code)
...
if (opt_list && opt_list->data[OPT_CODE] == code)

So yes, OPT_CODE and D6_OPT_CODE are both 0, but the D6_OPT_CLIENTID =
1 value means that the 1 is in the seconds byte, and udhcp_find_option
is only looking at the first byte,  So the send_d6_release can never
find it the created option.

9b67880719 Makefile.flags: use all cflags for crypt and rt checks
To check if libcrypt and librt are available, we check if we can
compile and link a simple test program.

These checks do not match the actual linking if CONFIG_STATIC is enabled.
For CONFIG_STATIC, CFLAGS_busybox is set to -static. The checks don't use
CFLAGS_busybox and detect a shared libcrypt or librt. If we link busybox
later and we have no static libcrypt or librt, linking will fail.

Update the libcrypt and librt checks to use CFLAGS_busybox.
