Take an incoming const char * pointer and return an allocated
array that must be freed. Don't expose the internal optimization
of file_lines_parse_internal() breaking the passed in string
into lines.

Make the internal function file_lines_parse_internal().
Currently file_lines_parse() just wraps file_lines_parse_internal(),
but this allows me to change file_lines_parse() to take
a const char * to make it safe for callers (no talloc tricks).

Almost all the callers are debug tools or developer debugging aids
and these callers clearly expect to create a new file.
Unchanged in behaviour is:
- TLS certificate creation. This already confirms the files do no exist
prior to generation.
These will now no longer overwrite the given filename
- net ads pac save
- net eventlog export

Triggered by two coverity false positives. Loading both files into
talloc'ed memory seems inefficient to me. Rely on stdio to do proper
buffering. This removes the restriction from ae95d611: "It is meant for
small files".
This is more lines, but to me it has less implicit complexity.

One case needs a variable declared, so it can be compared to -1 and
then cast to size_t for comparison.

Duplicate code to file_pload() except uses vectored
argument list. file_pload() will be removed once all
callers are converted.

and following. This also fixes a small and very theoretical race: Between the
fstat and the read call the file size might change. This would make us fail on
potentially legitimate files.
This is more complex and probably slower, but looking at the use cases I don't
think the speed matters.

file_pload() is static private function in Samba3 library, however it
does not have any special dependencies and might be widely used as
common function, so moving it into common samba-util library.

If the final line of a file does not contain a newline then it isn't
included in the line count.
Change i to point to the next slot in the array instead of the current
one. This means that that the current line won't be thrown away if no
newline is seen.
Without changing i to unsigned int, the -O3 --picky -developer build

Copy x_fgets_slash with conversion to stdio and talloc.
Probably I'd do this functionality a bit differently, but for simplicity I
chose to make it the same as what is there.
