9d8cc87758 add locate-source cache and line+column components to source objects
Add optional beginning-line and beginning-column components to a
source object, so that line and column information can be recorded
independent of the file. Add `locate-source-object-source` to use
the recorded information. Add a cache for `locate-source` as enabled by
the `use-cache?` optional argument, which can avoid compilation times
that are quadratic in the number of `let-values` or `define-values`
forms.

274322e06d fix (define-values () ....) to expand to a definition
Expanding to a definition means that it doesn't interrupt a definition
sequence.

59c772ba48 add make-ephemeron-eq-hashtable, etc.
Revert the use of ephemeron pairs in weak hashtables, since the
difference is visible via guardians. Add hashtable based on ephemerons
(to avoid key-in-value problems) as an explicit variant.

dacb66ac72 fixed a bug in flonum-extractor, which on 64-bit machines was using an
8-byte read instead of a 4-byte read to pick up the 4 highest-order
bytes of a little-endian flonum, potentially reading past the end of
mapped memory for flonums produced by taking the imaginary part of an
inexact complexnum (which, unlike other flonums, are not aligned on
16-byte boundaries).  The 8-byte load would also have failed to produce
correct results on 64-bit big-endian machines (of which we presently
have none) because the offsets passed to flonum-extractor assume the
bits are in the lowest-order 4 bytes of the extracted field.

b4d452cc71 - eliminated a couple of thread-safety issues and limitations on the
sizes of pathnames produced by expansion of tilde (home-directory)
  prefixes by replacing S_pathname, S_pathname_impl, and S_homedir
  with S_malloc_pathname, which always mallocs space for the result.
  one thread-safety issue involved the use of static strings for expanded
  pathnames and affected various file-system operations.  the other
  affected the file open routines and involved use of the incoming
  pathname while deactivated.  the incoming pathname is sometimes if not
  always a pointer into a Scheme bytevector, which can be overwritten if a
  collection occurs while the thread is deactivated.  the size limitation
  corresponded to the use of the static strings, which were limited to
  PATH_MAX bytes.  (PATH_MAX typically isn't actually the maximum path
  length in contemporary operating systems.)  eliminated similar issues
  for wide pathnames under Windows by adding S_malloc_wide_pathname.
  consumers of the old routines have been modified to use the new
  routines and to free the result strings.  the various file operations
  now consistently treat a pathname with an unresolvable home directory
  as a pathname that happens to start with a tilde.  eliminated unused
  foreign-symbol binding of "(cs)pathname" to S_pathname.
    io.c, externs.h, new_io.c, prim5.c, scheme.c, prim.c
- various places where a call to close or gzclose was retried when
  the close operation was interrupted no longer do so, since this can
  cause problems when another thread has reallocated the same file
  descriptor.
    new_io.c
- now using vcvarsall type x86_amd64 rather than amd64 when the
  former appears to supported and the latter does not, as is the
  case with VS Express 2015.
    c/Mf-a6nt, c/Mf-ta6nt
- commented out one of the thread mats that consistently causes
  indefinite delays under Windows and OpenBSD due to starvation.
    thread.ms
