    chicken: Update to version 5.2.0

    Changelog:

    5.2.0

    - Core libraries
      - Fix `memory-statistics` by returning semi-space bytes and used
        semi-space bytes like the documentation says. Old implementation
        returned full-heap size and (full-heap - used-semi-space).
      - for-each and map now behave consistently in compiled and interpreted
        mode, like in SRFI-1.  They now stop when the shortest list is
        exhausted instead of raising an exception (fixes #1422).
      - There is now a srfi-88 module which contains just the three
        procedures from the (chicken keyword) module defined by the SRFI.
      - A feature identifier named "srfi-88" is now registered.
      - The procedures `record-printer` and `set-record-printer!` and a
        corresponding SRFI-17 setter have been added. These deprecate
        `define-record-printer` which isn't a "real" definition (see #1294).
      - On Windows, `decompose-directory` no longer crashes when a drive
        letter is present in the supplied path string.
      - irregex-replace[/all] have been fixed for empty matches, so they
        will no longer drop characters and ignore the replacement (#1661).
      - Irregex has been updated to upstream 0.9.7, which also improves
        how empty matches are treated in irregex-fold and irregex-split.

    - Runtime system
      - Quoted empty keywords like ||: and :|| are now read like prescribed
        by SRFI-88 in the corresponding keyword mode.  Symbols containing
        quoted empty prefixes or suffixes like ||:abc and abc:|| will be
        read correctly as symbols now (fixes #1625, thanks to Andy Bennett).
      - IEEE floating point negative zero is now properly handled: it can
        be read, written and distinguished by eqv? and equal?, but not =
        (fixes #1627, thanks to John Cowan).
      - ##sys#check-exact and its C implementations C_i_check_exact and
        C_i_check_exact_2 have been deprecated (see also #1631).
      - When garbage collector is manually invoked from a finalizer, raise
        an error instead of hanging forever (fixes #1586).
      - define-record-type will now give an error if the constructor
        definition refers to field that's not listed elsewhere (see #1633)
      - Added new -:hu option to set the memory usage low watermark
        percentage at which the heap should be shrunk, and changed the
        calculation to actually reflect this (see #1379).

    - Compiler
      - Fixed a bug in lfa2 pass which caused "if" or "cond" nodes to be
        incorrectly unboxed if the "else" branch had a flonum result type
        (#1624, thanks to Sven Hartrumpf)
      - Inline files no longer refer to unexported foreign stub functions
        (fixes #1440, thanks to "megane").
      - In some cases, rest argument lists do not need to be reified, which
        should make using optional arguments and case-lambda faster (#1623).
      - Values from foreign types which have an argument or return value
        converter are no longer inferred to have the Scheme type which
        corresponds to the raw foreign type, which was incorrect (#1649).

    - Module system
      - Trying to export a foreign variable, define-inlined procedure or
        define-constant variable gives a friendly error instead of saying
        the variable doesn't exist (fixes #1346).
      - When modules are registered, they no longer pollute the global
        environment with imports made in that module (fixes #1548)

    - Tools
      - The new "-module-registration" options causes module registration
        code to always be included in the program, even when it has also
        been emitted as a separate file (for example with "-J").
      - chicken-install now correctly checks server response code to avoid
        interpreting error response bodies (like 404, 500) as Scheme code.
      - chicken-install now follows HTTP redirects when downloading eggs.
      - chicken-install will now change to the correct drive before
        attempting to change to the egg directory (fixes #1647).
