fbd1f5b486 util: file: use VIR_AUTOPTR for aggregate types
By making use of GNU C's cleanup attribute handled by the
VIR_AUTOPTR macro for declaring aggregate pointer variables,
majority of the calls to *Free functions can be dropped, which
in turn leads to getting rid of most of our cleanup sections.

b6d96ec80a util: file: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC
Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope.  Also, drop the redundant
viralloc.h include, since that has moved from the source module into the
header.

When a variable of type virFileWrapperFdPtr is declared using
VIR_AUTOPTR, the function virFileWrapperFdFree will be run
automatically on it when it goes out of scope.

e36bb5c572 cfg.mk: variable initialization when declared with cleanup macro
A variable, which is never assigned a value in the function, might get
passed into the cleanup function which may or may not raise any errors.

To maintain the correct usage, the variable must be initialized, either
with a value or with NULL. This syntax-check rule takes care of that.
