4ee1b4cac2 bootconfig: Cleanup dummy headers in tools/bootconfig 
Cleanup dummy headers in tools/bootconfig/include except
for tools/bootconfig/include/linux/bootconfig.h.
For this change, I use __KERNEL__ macro to split kernel
header #include and introduce xbc_alloc_mem() and
xbc_free_mem().

Replace u16 and u32 with uint16_t and uint32_t so

80be5998ad tools/bootconfig: Define memblock_free_ptr() to fix build error 
The lib/bootconfig.c file is shared with the 'bootconfig' tooling, and
as a result, the changes incommit 77e02cf57b ("memblock: introduce
saner 'memblock_free_ptr()' interface") need to also be reflected in the
tooling header file.

So define the new memblock_free_ptr() wrapper, and remove unused __pa()
and memblock_free().

824afd55e9 tools/bootconfig: Fix a build error accroding to undefined fallthrough 
Since the "fallthrough" is defined only in the kernel, building
lib/bootconfig.c as a part of user-space tools causes a build
error.

Add a dummy fallthrough to avoid the build error.

15e95037b4 tools/bootconfig: Remove unneeded error message silencer 
Remove error message silent knob, we don't need it anymore
because we can check if there is a bootconfig by checking
the magic word.
If there is a magic word, but failed to load a bootconfig
from initrd, there is a real problem.

a91e4f12ff bootconfig: Allocate xbc_nodes array dynamically 
To reduce the large static array from kernel data, allocate
xbc_nodes array dynamically only if the kernel loads a
bootconfig.

Note that this also add dummy memblock.h for user-spacae
bootconfig tool.

17d25ae7f1 tools/bootconfig: Fix wrong __VA_ARGS__ usage 
Since printk() wrapper macro uses __VA_ARGS__ without "##" prefix, it causes
a build error if there is no variable arguments (e.g. only fmt is
specified.) To fix this error, use ##__VA_ARGS__ instead of __VAR_ARGS__.
