As well as `#column_major matrix[R, C]T` as an alias for just `matrix[R, C]T`.
This is because some libraries require a row_major internal layout but still want to be used with row or major oriented vectors.
`path_to_fullpath` did different things on Windows&Unix, an attempt to
bring them closer together was made here.
This was prompted by the compiler completely ignoring
`foreign import "foo.dylib"` when `foo.dylib` does not exist (because
`path_to_fullpath` returns an empty string).
Causing just unresolved symbol errors, when on Windows it would pass
along the path to the linker and actually say it doesn't exist, which
is now also the case for Unix.
This also fixes some checker errors that relied on the Windows
behaviour, for example: `Error: File name, , cannot be as a library name
as it is not a valid identifier`.
Made `-no-crt` require either `-default-to-nil-allocator` or
`-default-to-panic-allocator` on Unix, the current default allocators
rely on libc and this was not obvious and would immediately bring up
unresolved symbol errors for the linked memory management functions, or
just link with libc anyways because it was foreign imported.
Added a suggestion to install `nasm` with the user's package manager
when assembling using `nasm` fails on Unix, I saw some confusion about
it in the Discord.
Ignore explicit foreign imports of libc. It is already linked in later
on in the linking process and would otherwise (at least on macOS) cause
linker warnings for duplicate libraries. This also makes it so when
using `-no-crt` and importing something that requires libc, linker
errors are given (like I would expect), instead of silently still
linking with libc because it was foreign imported.
A new package `core:time/datetime` has been added which can represent moments much further in the past and future than `core:time`.
It is based on *the* reference work on the subject, Calendrical Calculations Ultimate Edition, Reingold & Dershowitz.
More procedures will be added to it in the future, to for example calculate the 3rd Thursday in March to figure out holidays.
The package has been tested for more than a year and can handle dates 25 quadrillion years into the past and future with 64-bit day ordinals, or 5 million with 32-bit ones.
This also fixes a longstanding bug where converting between YYYY-MM:DD hh:mm:ss and `time.Time` and back could result in a mismatch.
RFC 3339 timestamps can now also be parsed using the `core:time` package.
_sys_open_mode() does exactly what sys_open() was originally doing
inline, I simply factored it into a separate function so that other
wrappers could call it (similar to _sys_permission_mode())
