Using `call-in-continuation` to apply a thunk within a continuation
slightly simplifies and speeds up parts of the implementation of
delimited continuations.
This operation effectively allows sending an expression back to a
continuation, instead of just a value. It's the same as Marc Feeley's
`continuation-slice` operation, but adjusted slightly to support
continuation attachments.

The expansion of `struct` created far too much code to parameterize
`struct-field-index`, making expansion of a `struct` form with just
100 or 200 fields take a noticeably long time to expand.
Also, remove signatures from primref. Now the record is reverted to the one in
the main ChezScheme version.
And lift most of the code outside the cptypes function.

The implicit counter to number the prelex has caused problems in the multithread
version many times, so make it an explicit arguments of the functions that is
passed around until the prelex-counter function uses it.
Perhaps it can be remover later, after rewriting the implementation of
define-specialize.

While "\44\26\2\f6" currently works as a terminator for non-compressed
fasl streams, the working byte sequence varies as the fasl format
changes. Add "\177" as a simpler and unchanging terminator.

- the collector now releases bignum temporaries in the collector
rather than relocating them so we don't keep around huge bignum
temporaries forever.
gc.c
- removed the presumably useless vector-handling code from load()
which used to be required to handle fasl groups.
scheme.c
- object files are no longer compressed as a whole, and the parameter
compile-compressed is no longer defined. instead, the individual
fasl objects within an object file are compressed whenever the
new parameter fasl-compressed is set to its default value, #t.
this allows the fasl reader to seek past portions of an object
file that are not of interest, i.e., visit-only code and data
when "revisiting" an object file and revisit-only code and data
when "visiting" an object file. the compressed portions are
compressed using the format and level specified by the compress-format
and compress-level parameters. the C-coded fasl reader and
boot-file loader no longer handle compressed files; these are
handled, less efficiently, by the Scheme entry point (fasl-read).
a warning exception is raised the first time a program attempts
to create or read a compressed fasl file.

- added begin wrappers around many of the Scheme source files that
contained multiple expressions to cut down the number of top-level
fasl objects and increase compressibility. also removed the
string filenames for debugging at the start of each file that had
one---these are best inserted universally by a modified compile-file
during a debugging session when desired. also removed unnecessary
top-level placeholder definitions for the assignments that follow.

PR #2678 unintentionally removed this attribute, but it was used
at least by "collections-lib" and "static-rename-lib".

- reword the first-page explanation of chaperone contracts;
try to give a positive description by talking about wrappers first
(rather than starting with what chaperones maybe don't do)
- name the recognizer functions for chaperone & impersonator contracts
(on the first page)
- clarify that `contract-projection` and `contract-val-first-projection`
are bad --- that there's a preferred alternative
- describe the outputs of `contract-projection` and
`contract-val-first-projection`; their docs were identical before, but
now re-use prose from sec 8.7 (Building New Contract Combinators)
Use a consistent style for the "good / bad" examples:
- start the code at the far left of each box
- keep a little space between the top of the box & the label
GitHub's CDN seems to have recently started returning the `Location` header for a redirect with a lowercase `l`, which breaks the redirect logic. The HTTP spec says that header names are case-insensitive, so we need to look for either version.
Commit 72d90e4 ("library-manager, numeric, and bytevector-compres
improvements") introduced a regression causing Win32 nmake builds to
fail due to an undefined symbol in c\schsig.c.
This symbol (scheme_signals_registered) is defined in a preprocessor-
conditional code block excluding WIN32 between lines 544 and 737.
This commit bypasses the build regression by enclosing the unresolved
expression in a preprocessor conditional excluding WIN32.
See GitHub Issue #497 for more details:

original commit: 10bccf39badee76f80d87326d2fc7c4d808fa08e
Make `register-process-global` check for byte strings, and avoid
retaining the byte string that it's given (in case that changes, for
example).
Closes#3053
