Log Message:
chicken5: update to 5.4.0

Packaging Changes:
- removed patch-egg-compile.scm since upstream has fixed this.

Upstream Updates:
- Security fixes
  - CVE-2022-45145: Neutralize possible escape characters in egg metadata
    to avoid arbitrary OS command injection during egg installation,
    reported by Vasilij Schneidermann who also provided the necessary
    patches to mitigate this problem.
  - The runtime option "-:b" has been removed, as it was deemed too
    insecure to be able to drop to a REPL from the CLI of any program.
  - Runtime option processing has been hardened: processing now stops on
    the first non-runtime option or after "-:", whichever comes first.

- Core libraries
  - Fix type declarations for `file-select` (reported by Anton Idukov).
  - Change `create-temporary-{file,directory}` fallback code on Windows to
    use %USERPROFILE%/AppData/Local/Temp if that environment variable is set.
  - Added new thread-safe API for POSIX signals ("make-signal-handler",
    "signal-ignore" and "signal-default") and deprecated the \ 
existing one.
  - Added "make-finalizer" to execute finalizers in a thread-safe
    manner.
  - Added weak pairs to (chicken base), with similar behaviour to Chez Scheme.
  - Added "locative-index", kindly contributed by John Croisant.
  - Added "fp*+" (fused multiply-add) to "chicken.flonum" module
    (suggested by Christian Himpe).
  - Added flonum-specific hyperbolic functions and their inverse to
    "chicken.flonum" module (suggested by Christian Himpe).
  - The `process-execute` procedure now sets argv[0] to the unmodified
    filename. Previously, the directory part would be stripped.
  - Added support for embedded strings and characters in SRFI-4 vector
    literals.
  - read-with-source-info is now documented and officially supported,
    from the (chicken syntax) module.  read/source-info is still exported
    from the undocumented internal (chicken compiler support) module, but
    using it from there is deprecated.
  - Added "export/rename" to (chicken module) for renaming identifiers on
    export.
  - The values of the TMPDIR, TMP and TEMP environment variables are no
    longer memoized (fixes #1830).
  - Condition objects produced by procedures that change errno now have
    an `errno' property.
  - Deprecated "chicken-home" and added "include-path" in the
    chicken.platform module.
  - Irregex has been updated to upstream 0.9.11 plus an additional fix
    for sre->string.  The 0.9.11 release fixes a few problems related to
    utf-8 handling (which should not affect CHICKEN) and expands the
    definition for the 'whitespace character set to include vertical tab,
    carriage return and form feed.

- Tools
  - Fix scripts generated by `chicken-install` on Windows to not quote `>>`
    when echoing into files which would result in empty egg-info files
    (reported and fixed by Jani Hakala).
  - The -R option for csi and csc now accepts list-notation like
    e.g. (srfi 1).  Fixes #1809, reported by Wolfgang Corcoran-Mathe.
  - Fix shell quotation in options passed from csc to other tools.
    Fixes #1302, reported by Xin Wang.
  - The -prelude and -postlude options for csc work properly again.
  - chicken-install now retrieves the latest egg version when
    instructed to install an egg that's already installed (#1802).
  - When `location' is specified in setup.defaults, chicken-install
    will consider two location layouts when looking for eggs:
    <location>/<egg> and <location>/<egg>/<version>.
  - chicken-install: Fix #1684 (programs that specify
    component-dependencies should build-depend on their import
    libraries).
  - chicken-install now caches eggs installed from local locations.
  - chicken-install now accepts the -location command line option
    (short: -l) to specify local directories where to get egg sources
    from.
  - chicken-install now gives a warning on unexpected properties (#1492).
  - chicken-install now uses a directory specific for cache metadata
    (VERSION, STATUS and TIMESTAMP files) to avoid collisions with source
    files on case-insensitive file systems like on MacOS (#1753, reported
    by Kon Lovett).

- Syntax expander
  - When passing a module as an environment to eval, correctly resolve
    identifiers in macro expansions (#1295 reported by Caolan McMahon).
  - Internal definitions honor rebindings of core special forms (#1132).
  - Globally defining an identifier previously bound to a macro now fully
    shadows the macro (#1166, reported by Michele La Monaca).

- Compiler
  - When emitting types files, the output list is now sorted, to ensure
    deterministic build output (fixes #1783, reported by "ss2").

- Build system
  - Fix compiler warnings about zero-sized `memset` (reported by Claude Marinier).
  - Disable broken test-create-temporary-file on Windows (reported by \ 
"jjhoo").
  - Drop use of XCODE_... environment variables on MacOS.
  - Add build directory to rpath on MacOS so that the test suite picks up correct
    libchicken, even if CHICKEN is already installed (thanks to Christian Himpe).
  - Default "cc" on BSD systems for building CHICKEN to avoid ABI problems
    when linking with C++ code.

- Runtime system
  - Make line numbers available for error output and during syntax expansion
    in the interpreter as well as the compiler.
