5df955fce2 Do not fail password check if shadow password does not exist -
fall back to ordinary one

Reduced usage of functions returning datain static buffers.
(mostly passwd/group/shadow related):

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

Hi Erik,
Hi to all,
This is part five of the my_get*id story.
I've tweaked a bit this two functions to make them more flexible,
but this changes will not affect existing code.
Now they work so:
1) my_getpwuid( char *user, uid_t uid, int bufsize)

   if bufsize is > 0 char *user cannot be set to NULL
                     on success username is written on static allocated buffer
                     on failure uid as string is written to buffer and NULL is returned
   if bufsize is = 0 char *user can be set to NULL
                     on success username is returned
                     on failure NULL is returned
   if bufsize is < 0 char *user can be set to NULL
                     on success username is returned
                     on failure an error message is printed and the program exits

  2) 1) my_getgrgid( char *group, uid_t uid, int bufsize)

   if bufsize is > 0 char *group cannot be set to NULL
                     on success groupname is written on static allocated buffer
                     on failure gid as string is written to buffer and NULL is returned
   if bufsize is = 0 char *group can be set to NULL
                     on success groupname is returned
                     on failure NULL is returned
   if bufsize is < 0 char *group can be set to nULL
                     on success groupname is returned
                     on failure an error message is printed and the program exits

This changes were needed mainly for my new id applet.
It is somewhat bigger then the previous but matches the behaviour of GNU id
and is capable to handle usernames of whatever length.
BTW: at a first look it seems to me that it will integrate well (with just a few changes)
with the pending patch  in patches/id_groups_alias.patch.
The increase in size is balanced by the removal of my_getpwnamegid.c
from libbb as this was used only in previous id applet and by size optimizations
made possible in whoami.c and in passwd.c.
I know that we are in feature freeze but I think that i've tested it enough
(at least I hope so.......).

d378c3149c Applied vodz' patches #49 and #50 (with a small correction in runshell.c)
#49: I found one memory overflow and memory leak in "ln" applet.
Last patch reduced also 54 bytes. ;)

#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.
