Alejandro Colomar 093fb605f9 lib: Merge libmisc into libshadow
The separation was unnecessary, and caused build problems.  Let's go
wild and obliterate the library.  The files are moved to libshadow.

Scripted change:

$ find libmisc/ -type f \
| grep '\.[chy]$' \
| xargs mv -t lib;

Plus updating the Makefile and other references.  While at it, I've
sorted the sources lists.

/*
* According to the Linux-PAM documentation:
*
* 4.1. Care about standard library calls
*
* In general, writers of authorization-granting applications should
* assume that each module is likely to call any or all 'libc' functions.
* For 'libc' functions that return pointers to static/dynamically
* allocated structures (ie. the library allocates the memory and the
* user is not expected to 'free()' it) any module call to this function
* is likely to corrupt a pointer previously obtained by the application.
* The application programmer should either re-call such a 'libc'
* function after a call to the Linux-PAM library, or copy the structure
* contents to some safe area of memory before passing control to the
* Linux-PAM library.
*
* Two important function classes that fall into this category are
* getpwnam(3) and syslog(3).
*
* This file provides wrapper to the prefix_getpwnam or prefix_getpwnam_r functions.
