fs_shell: Use proper readv/writev functions on Haiku hosts.

Fixes #18269.

libroot_build & fs_shell: Provide _kern_ functions for readv/writev...

..instead of readv_pos/writev_pos. This way, we can be sure that we
are remapping them properly even under Haiku, as well as remove some
potential confusions.

bfs_shell seems to still work fine on a regular build.

Remove conditions for HOST_PLATFORM=msys.

It never really worked beyond the most basic of commands
and required a lot of hacks, and these days WSL should be used instead.

build: More miscellaneous fixes for MSYS.

Remove the .exe hack, as it is not needed.

tools: Fixes following build syscall change.

build/kernel: Properly shadow syscall functions.

I didn't notice this in the previous commit because apparently GCC2
just links against libroot's versions of them. On GCC5, however,
the version from libroot_build was used even for calls from libroot itself,
which led to infinite loops and then stack overflows.

So instead we must have the "syscall" functions in libroot_build shadow
the real ones by being named differently, which I did by changing their
prefix from "_kern" to "_kernbuild" via preprocessor macros.

Since the build syscalls.h is now substantially different than the non-
build one (and has not been synchronized in nearly a decade anyway),
I've just stripped out all the syscall defns except for the ones actually used
in the build.

Thanks to kallisti5 for helping me debug and test.

* This fixes my last change...

* The fs_shell is now always using BLKGETSIZE64 on Linux, and only if that fails
it will fall back to HDIO_GETGEO.
* This fixes incorrectly reported disk sizes for a number of disks I have here.
Please open a bug report if this change causes problems for you (we would then
have to check the kernel version to choose the preferred method).

<sys/ioctl.h> also seems to be the standard Linux place for the
ioctl() prototype. Apparently some Linuxes discarded the <stropts.h>
header which POSIX demands.

Linux.

Not so in BeOS/Haiku, but officially ioctl() is defined in <stropts.h>.

Patch by Samuel Rodriguez Perez: Added support for writing Haiku
directly onto a device under FreeBSD.

I messed around with the code a little (style-fixes, some refactoring)
without being able to compile or test it, so be careful...

The fs_shell now also works with devices that don't return a correct
hd_geometry, but do support the BLKGETSIZE64 ioctl (it just crashed
before).

* Added mapping of dup() in the FS shell.
* Adjusted the FS initialize() hook to have FD and partition_id
parameters like the other hooks instead of the partition path.
* Adjusted initialization in BFS accordingly.
* Implemented the FS initialization method in KFileSystem.

* Moved the syscalls into the FSShell namespace, so that they don't
collide with the functions defined in libroot_build.so.
* On BeOS incompatible platforms fssh_open() and fssh_close() use the
libroot_build.so _kern_open() and _kern_close() respectively, so that the
attribute support works also when using the generic attribute
emulation.
* Use fssh_open()/fssh_close() instead of open()/close() for the cp
command, so that we get attribute support on BeOS incompatible
platforms when the generic attribute emulation is used.

BeOS build fixes:
* On BeOS compatible host platforms we must not include

* Fixed errno usage in command_cp.cpp.
* Fixed fssh_ioctl().
* fssh_set_sem_owner() doesn't invoke BeOS's set_sem_owner() anymore or
otherwise the FS's semaphores are assigned to the kernel.
* Commented out <string.h> functions that don't exist under BeOS (and aren't
used anyway).
