The %x specifier expects an unsigned argument. If char is signed,
cmocka_print_error() may incorrectly display values sign-extended. To
fix this, use an unsigned char and the corresponding format specifier
(%hhx).

Disable `-Wdeclaration-after-statement`.

Before ISO C99, declaring variables after statements was not allowed
by the C standard, but was allowed by GCC as an extension.

CMocka now requires a minimum version of C99,
since commit 5a4b1587

, so this
behaviour is valid on all compilers.

Projects using cmocka could have done this successfully from version 1.0 to
1.1.5 to build against cmocka:

```
find_package(cmocka 1.0 REQUIRED CONFIG)
```

and later

```
target_link_libraries(myapp
	${CMOCKA_LIBRARIES}
)
```

Modern apps should just "link" against 'cmocka::cmocka' instead like it's done in
examples already.  To not break old builds (as it is the case with cmocka
release 1.1.7) we can put that modern target string into the variable
CMOCKA_LIBRARIES and thus trick old projects to just use that, keeping
compatibility until those projects explicitly use the modern version.

Makes the implementation behave the same like libc calloc() and not fail with
unpredictable errors in test_malloc() anymore.

(cherry picked from commit 6ff1378b)

calloc() is prone to integer overflow on multiplication of its arguments.
glibc, musl, and uclibc test for that in its implementations and return NULL in
that case with errno set to ENOMEM.  cmocka lacks such a check and passes all
kinds of overflown values to test_malloc() with different ways to fail.

Fixes #86

Signed-off-by: Andreas Schneider <asn@cryptomilk.org>

This way compilers should not mark it as unreachable.

This fixes path relocation in mingw environment by using predefined
Libs and Cflags variable in pkgconfig file. Otherwise, libdir and
includedir are not shown in pkgconf output. e.g.
* Without predefined variables:
  - pkgconf -cflags cmocka: No output
  - pkgconf -libs cmocka: -lcmocka
* With predefined variables:
  - pkgconf -cflags cmocka: -IC:/msys64/mingw64/include
  - pkgconf -libs cmocka: -LC:/msys64/mingw64/lib -lcmocka

Also official documentation suggests to use predefiend keywords here
