fe8c991a11 Fixes possible buffer overrun when source string too long
If the Lisp string passed to LispStringToCString were longer than
  the destination buffer's MaxLen the could would have written the
  terminating nul past the end of the array.

  Fixes formatting of LispStringToCString

  Corrects English grammar in some comments.

364bc1f31c Removes StrNCpyFromLispToC(), renames StrNCpyFromCToLisp to MemCpyToLispFromNative
Removes StrNCpyFromLispToC and the single use of it in
LispStringToCString in the BYTESWAP implementation case.

Rename StrNCpyFromCToLisp, which does NOT follow "strncpy" semantics,
to be MemCpyToLispFromNative, where the types in the name match the
types of the arguments, and the semantics (and argument order) are
those of the C library "memcpy".

4994982a90 Adds the non-keypad arrow keys to be detected.
With additional Medley calls to KEYACTION (below), they should work in TTYIN (i.e., XCL and Interlisp EXECs).
I didn't try TEDIT.
They are unrecognized in SEDIT. (In any case, their use there probably is pretty restricted by the nature of SEDIT.)

(KEYACTION 'KEYPAD8 '(("Meta,^" 56 NOLOCKSHIFT) . IGNORE))
(KEYACTION 'KEYPAD6 '(("Meta,>" 54 NOLOCKSHIFT) . IGNORE))

511a1b523e Eliminate extra gotos in common branch tail code (#528)
The implementation of various JUMP opcodes tried to use a common tail
that did a POP and branched to the next opcode. While the extra gotos
probably aren't harmful, neither are they beneficial to code size or speed.

31bb14b9d7 Modifies Lisp exit subr to permit passing an exit status code (#524)
These changes add (LOGOUT <number>) to the traditional
(LOGOUT) and (LOGOUT T) calls.  If an integer <number> is provided
it will be used as the exit status code, while NIL and T result
in an EXIT_SUCCESS.

If the argument passed is none of NIL, T, or a number, the exit
status code will be a generic EXIT_FAILURE (typically 1).

(LOGOUT) and (LOGOUT T) virtual memory behavior is unaffected.
When a <number> is passed Lisp will exit without saving the
virtual memory state, as is the case for (LOGOUT T), although
this behavior is determined by Lisp rather than the Maiko emulator.

fae5c4956e Cleanup in the "version array" handling in the {DSK} device (#513)
* Remove useless VersionArray parameter in maintain_version()

The 2nd argument, FileName *varray, is only ever NULL, so
remove it and simplify the code.

* Remove useless and unused VersionArray cache mechanism

* Simplify setting of file times on file close

The futimes(fd, ...) function allows changing the times of a file with
reference to an open file descriptor which allows us to avoid trying to
find a pathname by which utimes(path, ...) would operate on the inode
corresponding to the fd we have just closed.

* Remove unnecessary temporary variable for VersionArray

* In get_version_array() do not mix array and pointer access to VersionArray

* Improve {DSK} device handling of files with many versions

Somewhat dynamically allocate the version array storage, in chunks of
VERSIONARRAYCHUNKLENGTH (currently 200) allowing for up to
VERSIONARRAYMAXLENGTH (currently 2000) entries before reporting an
error. These numbers could be adjusted, or the limit could be removed.

Sorts the version array in descending order of version number to
improve the performance of check_vless_link() which stats every file
in the version array until it finds one linked to the versionless name
(which should be the highest version).  Sorting, and tracking the
number of active entries, also allows for future optimization of other
operations that currently walk through the version array.

* futimens() appears more widely available than futimes() - so use it

* Rework caching of version array for files

While enumerating the entries in a directory is relatively fast,
on some systems (macOS) stat() of a file is slow.
While there is not general agreement on the name in the stat structure
of the timespec field for the modification time, POSIX specifies it
as "st_mtim", and it is possible to #define st_mtim to be the
system-specific name in "version.h" (macOS: st_mtimespec).

* FindHighestVersion can make use of sorted order of filename/version cache

Since the list of filename and versions is maintained in descending order
by version number (see get_version_array) the highest version is trivially
located at index 0 of the filename array.

86ba485c3e Replace "unsigned short" use for bit-fields with DLword
Where bit-fields are defined in a structure that represents a Lisp
DLword object the DLword type is now used as the base type instead of
"unsigned short".

b88ea87fa8 Remove USHORT definition and replace uses with DLword

aa4df518a1 Release 201 corrections (#510)
* Fix compilation for maiko version 201

Version 201 does not have BIGVM, so SWA_FNHEAD requires swapx
which is defined in byteswapdefs.h

* Fix compilation for maiko version 201

Version 201 did not have NEWCDRCODING, so the implementation of
N_OP_rplcons requires definitions from gcdata.h and address.h

* Set up makeright etc. to allow for easier compilation of alternate versions

The makeright script and the makefile-* slices it depends are modified
to allow easily specifying the RELEASE version number of the Maiko emulator
to be built.  The default version remains 351, but can be changed with e.g.

RELEASE=201 ./makeright x

The object directories and executables are NOT named with the version.

* Remove unnecessary include of gcdata.h from bbtsub.c

* Users of gcdata.h should include gchtfinddefs.h explicitly if they use gcdata.h macros

* Correct modify_big_reference_count entry parameter type to reflect dependence on GCENTRY size differences between releases

* Add MAIKO_RELEASE to CMake options for building

68baf6fb30 Use ...FromStackOffset functions where appropriate
Rather than adding/or-ing the STK_OFFSET constant into a stack offset
to convert it to a pointer in general Lisp memory and then converting
from that to a native address... use the functions specifically
present to do those conversions with embedded checks on stack offset
validity.

939c23c03b Additional check for bad stack offset calculation
Pointer difference calculations on an inappropriate stack pointer could
result in a negative offset, not just an offset that is too large to fit
in 16 bits.  Complain if either case occurs.

55591557b6 Clarify the expected size/packing of bit fields in stack structures
While packing is not guaranteed, and most compilers will combine
adjacent bit fields regardless of the alignment requirements of the
datatype that is being divided, here we can be clearer that we
expect packing into 16-bit fields and we do not require (and must not
have) 32-bit alignment of the collections of bitfields.

* Changes needed to compile maiko on Alpine Linux with clang.

Switching to Alpine on github actions to streamline maiko release builds.

  * ether_nethub.c missing a couple of includes, and incorrectly including

  * <dirent.h> does not define MAXNAMLEN on Alpine Linux, but "locfile.h"
    compensates for this already, if it is modified to include <limits.h>,
    so use this in "dirdefs.h".
