fclose: avoid double close race when possible
Calling close(fileno(fp)) prior to fclose(fp) is racy in a
multi-threaded application - some other thread could open a new file,
which is then inadvertently closed by the fclose that we thought

already present in close_fd_maybe_socket for calling closesocket()

nice and avoid the race.

quotearg: avoid uninitialized variable use
Coverity correctly deduced:
Error: UNINIT:
m4-1.4.16/lib/quotearg.c:171: var_decl: Declaring variable "o" without initializer.
m4-1.4.16/lib/quotearg.c:175: uninit_use: Using uninitialized value "o": field "o".right_quote is uninitialized.
When custom_quoting_style was introduced in commit
12247f77,
this method was not updated, and any caller that passed
the new enum value to any of the existing quotearg_*style
functions could trigger a crash from the uninitialized memory.
That was already documented as unspecified behavior, though,
so changing to an abort makes it easier to spot bad code that
passes the wrong enum value, rather than waiting for the
eventual bad memory dereference later on.
Most callers of quotearg_*style were using quoting_style_args
and quoting_style_vals to map strings to particular enum
values, and custom_quoting_style is (intentionally) not covered
by these arrays, so the pre-patch bug/post-patch abort are not
possible with those callers.

xalloc-oversized: new module
Due to inline functions, mere inclusion of xalloc.h can result
in a link dependency on xalloc_die() on some platforms. However,
there are several modules that want to use just xalloc_oversized
in order to short-circuit the potential to call xalloc_die.
Splitting the macro into a new header and module makes this easy.
* modules/xalloc-oversized: New module.
* modules/xalloc (Depends-on): Add it.

utimecmp: drop dependency on xmalloc
utimecmp's only use of malloc was for a cache; we can always bypass
the cache in low memory, and thus avoid dragging in xalloc-die.

due to memory pressure.

getcwd: fix mingw bugs
On mingw, getcwd(NULL,1) succeeds, even though glibc documents that
with a non-zero size, the allocation will not exceed that many bytes.
On mingw, getcwd has the wrong signature. However, we don't have
to check for this if anything else triggers the replacement.
Also, fix a type bug that crept into the original getcwd-lgpl commit.
