Mainly adding missing headers, removing redundant headers that
induce undefined symbols or rearranging existing headers
according to dependencies betheen them.
Also add missing include paths to makefiles and make configs.

Note: direct inclusion of pthread.h in disk.h is caused by the
latter being used almost everywhere, including third_party libraries.
Putting pthread.h there releases us from affecting more code.

Basically fixes build for anything that is not default HiSi
configuration.

If the platform doesn't support rootfs but shell and serial
console are enabled, create Shell task in kernel.
Note that normally, shell task is created by /bin/init.

Currently unused but when rootfs is enabled
we should get this error and quickly narrow down
where to add proper bootargs handling.

BSD compatibility is not optional for the kernel to build, however
platform dependent portion of this configuration, machine_resource_init(),
which is called by nexus_init() is implemented only in the platform
specific library for HiSilicon chips (libhi35xx_bsp.a).
Workaround lack of this library, so that the kernel can be built
for other platforms as well, by excluding it from the compilation.

This change should be removed as soon as the appropriate function
is implemented for other platforms.

During LiteOS consolidation, system_init.o object that contains
SystemInit() doesn't exist yet as it is being built later
and linked in ./vendor directory when OHOS_Image is created.
This is not the case when building for HiSilicon platforms as
SystemInit is provided for them in precompiled libraries.

Workaround this issue by creating "weak" function in LiteOS
that will be replaced by the "strong" symbol from ./vendor
in linking phase of the OHOS_Image.

conf --silentoldconfig generates required autoconf.h file
