The `--sync-docs-only` flag is intended for contexts like pkg-build as
a backstop against unintended and time-consuming activity when the
intent is to assemble documentation.
While sending an absolute path to a foreign library is usually the
right idea to ensure that it's relative to `(current-directory)`, the
`_path` FFI type should not do that automatically --- because
sometimes it's useful to send a relative path to a foreign library,
but most because it hasn't been defined that way in BC.
In building up conversion tables, information from "SpecialCasing.txt"
data was incorrectly merged with data from "UnicodeData.txt" so that
not-quite-so-special casings were fumbled. For Unicode 7.0, the bug
turned out to affect only string downcasing of U+1E9E.
Closes#3475
Thanks to Xsmith!
Changes to use xlocale fixed problems with places and locale settings,
but it caused the initial process-wide locale to stay with the C
locale, which is bad for things like libedit. To get the good part of
the old behavior bback, set the process-wide locale to "" on startup.
When an exact (non-integer) rational is reconstructed from a place
message, normalization could involve bignum operations --- and those
operations might use a cache, but the cache should not refer to the
pages that are specific to a place message being constructed.
Normalization isn't necessary, since the parts were already in a
rational, so the repair is just it skip it.

A table of subprocess handles to finalize was not place-local as it
should have been. The same was true of a table of resolved IP
addresses to finalize.

The Racket variant of Chez Scheme includes special treatment of deeply
nested structures to avoid a C-stack overflow on unfasl, but the
relevant callbacks had gotten mangled.
Closes#3454
When a would-be loop is called in a would-be loop that turns out not
to be a loop due to an intervening non-loop layer, the outer would-be
loop was not detected as a non-loop.
When the mutability decision on a variable is delayed, but then the
variable is discovered to be mutable before the delay is triggered,
then mutability information could get lost.
Mutability analysis may determine that a `set!` is dead code, and then
the mutated variable might be optimized away, so don't leave the dead
`set!` behind.
When the srcloc-enriched S-expression representation a function that
is available for cross-module inlining has a source that is not a
path, string, or symbol, then the source has to be dropped in the
module's serialized form.
On a 64-bit machine, the problem was a `<` versus `<=`.
On a 32-bit machine where 4294967087 is not a fixnum, the
problem was in how bignums are handled.
