Preprocessor magic is used to redirect putc/fputc/fputs/printf/fprintf
to custom implementations.
The custom implementations try to figure out if we are printing to the
console and, if so, convert the resulting strings to UTF-16 and print
them through ConsoleWriteW. If the output is redirected to a file or
a pipe, the original (presummed) UTF-8 is kept.
Simply setting the console output codepage to UTF-8 does not work,
because the standard I/O facilities of MSVCRT either does not support
unicode (in non-wchar mode), or has half-broken support through fputs,
which can still break up multi-byte sequences through its internal
buffering.
Likewise, changing the codepage and using ConsoleWriteA, or trying to
use fputws did not work in a test VM either.
This approach is the one that worked most consistently among the
ones tried, but also has problems. E.g. it breaks when setting the
codepage to UTF-8 manually (using `chcp 65001`).

Fix Windows main wrapper after mingw upgrade2021-12-14T19:54:40+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2021-12-14T19:44:04+00:00urn:sha1:8e1a2644968ce048feecd7f480ed4cce7dec7f6b
Apparently, mingw implicitly included stdlib.h indirectly from either
windows.h or shellapi.h. After an upgrade, the windows build now
fails with EXIT_FAILURE being undefined.

Add a wrapper for the main function on Windows2021-12-05T09:29:32+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2021-11-26T12:53:43+00:00urn:sha1:4a4dbe027a082e546512b5ccb2999753651a9a28
A macro and forward declaration are added to compat.h that rename
the main() function programs using compat.h into sqfs_tools_main.
An actual main() function is added to libcompat.a, that uses the
shell API to get the UTF-16 command line arguments, convert them
to UTF-8 and call sqfs_tools_main.

Cleanup: move overflow safe alloc code into libsquashfs2019-11-25T12:20:08+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2019-11-25T12:13:05+00:00urn:sha1:fc9a644002dc501a5c224e5cc1a7dfba3ca2d1d8
There were only a hand full of instances outside libsquashfs that used
the alloc code. In most cases, the thing allocated hat its size derived
from something already in memory anyway, so it is safe to assume its
size fits into a size_t.
At the same time, the opencoded Windows path conversion functions are
all unified into a single helper function.
