Run sparse against source files when building e2fsprogs with 'make C=1'. If
instead C=2, it configures basic ext2 types for bitwise checking with sparse,
which can help find the (many many) spots where conversion errors are
(possibly) happening.

If secure_getenv() use it in preference to __secure_getenv().
Starting with (e)glibc version 2.17, secure_getenv() exists, while
__secure_getenv() only works with shared library links (where it is a
weak symbol), but not for static links with /lib/libc.a

Commit a7c17431b9 attempted to fix a problem where the system
libraries might get used instead of local libraries for things like
-lcom_err. It tried to accomplish this by moving $(ELF_OTHER_LIBS) to
before $(LDFLAGS).
Unfortunately, this was the wrong fix; $(ELF_OTHER_LIBS) *MUST* be
after the object files, or the linker might not pull in the necessary
library and not include it into the DT_NEEDED section of the shared
library. The proper fix is to add a -L$(LIB) before $(LDFLAGS), and
then remove the -L option from all of the ELF_OTHER_LIBS definitions
in the library Makefiles.

Change the include path in the Cflags field so that #include
<lib/foo.h> and <foo.h> will work. We had originally used a C flags
which allowed <foo.h> to work, but many applications (especially those
not using pkg-config) had been using the <lob/foo.h> formulation which
didn't require an explicit -I{$includedir} option to the C compiler.
If those applications then converted over to pkg-config, and the
e2fsprogs libraries were installed with a prefix other than /usr, so
that the header files were in some directory such as
/usr/local/include, a program that used #include <lib/foo.h> would
fail to compile.
So change the pkg-config files to include both -I{$includedir} and
-I{$includir}/lib.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

Some people don't want to see the concise "kernel-style" make output.
This configure option allows build engines that want to see the full
set of commands executed by the makefile to get what they want. Most
people will find this more distracting than useful, unless they need
to debug the Makefiles.
(It is not necessary to rerun configure to enable this verbose make
output temprarily; if a developer wants to do a quick debug of a
directory's makefile, he or she can simply edit the definition of the
$(E) and $(Q) variables in the Makefile; instructions can be found in
the MCONFIG file which is included in at the beginning of every
Makefile.)

The e2fsprogs makefiles were using the same Makefile variable
LIBCOM_ERR for the link-line arguments as well as the dependencies.
Since LIBCOM_ERR can now include non-file arguments such as
"-lpthread", we need to use a separate DEPLIBCOM_ERR variable that
only has build file dependencies.
Do the same thing for STATIC_LIBCOM_ERR and PROFILED_LIBCOM_ERR.

Gcc is too stupid to realize that:

com_err(progname, 0, usage);
is OK. I refuse to bow to stupidity with:
com_err(progname, 0, "%s", usage);
but I will use the string directly for the sake of people who like to
build with -Werror=format-security.

Fix a memory leak by freeing the argv[] array if ss_parse_line returns 0
for argc 0 (which will happen if the user his return and sends an empty
line to the application).
Potentially need to free argv before early return since it was allocated
memory. Need to be careful since it may be possible for ss_parse() to have
freed the memory allocated to it if it detects an unbalanced set of quotes
passed to it.

Looks like flawed reasoning. Here if info_dir is NULL then you are
guaranteed to blow up since you will dereference it. It seems like the
correct thing to do here (what the code author meant to do) was to set
*code_ptr = SS_ET_NO_INFO_DIR if info_dir was NULL or if *info_dir was
an empty string (aka *info_dir == '\0').

environment variables if the libraries are called from setuid or setguid
programs, or if kernel believes that the process is not eligible to create

the libc can also do any additional limitations regarding when libraries can
trust environment variables (i.e., to integrate with systems like SELinux
and Posix capabilities).
