checkpatch.pl lints for spaces around operators including / (slash).
Code lines starting with #include are ignored, as slashes in those
represent path separators.
In Objective-C code, #import is often used in preference to #include,
as preprocessor-based multiple-#include defenses are considered
non-idiomatic in that language.
This change extends checkpatch.pl to treat #import lines in the same
way as #include, avoiding false positives for "missing" spaces
around path separators on those lines.

Commit d424db2354 removed an instance of strerrorname_np() because it
was breaking building with musl libc. A recent RISC-V patch ended up
re-introducing it again by accident.
Put this function in the baddies list in checkpatch.pl to avoid this
situation again. This is what it will look like next time:
$ ./scripts/checkpatch.pl 0001-temp-test.patch
ERROR: use strerror() instead of strerrorname_np()
#22: FILE: target/riscv/kvm/kvm-cpu.c:1058:

Add two spelling check options (--codespell and --codespellfile) to
enhance spelling check through dictionary, which copied the Linux
kernel's implementation in checkpatch.pl.
This check uses the dictionary at "/usr/share/codespell/dictionary.txt"
by default, if there is no dictionary specified under this path, it
will look for the dictionary of python3's codespell (This requires user
to add python3's path in environment variable $PATH, and to install
codespell by "pip install codespell").

Since commit 262a69f428 ("osdep.h: Prohibit disabling assert()
in supported builds") we can not build QEMU with NDEBUG (or
G_DISABLE_ASSERT) defined, thus 'assert(0)' always aborts QEMU.
However some static analyzers / compilers doesn't notice NDEBUG
can't be defined and emit warnings if code is used after an
'assert(0)' call.
Apparently such compiler isn't as clever with G_DISABLE_ASSERT,
so we can silent these warnings by using g_assert_not_reached()
which is easier to read anyway.
In order to avoid these annoying warnings, add a checkpatch rule
to prohibit 'assert(0)'. Suggest using g_assert_not_reached()
instead. For example when reverting the previous patch we get:
ERROR: use g_assert_not_reached() instead of assert(0)
#21: FILE: target/ppc/dfp_helper.c:124:
+ assert(0); /* cannot get here */
ERROR: use g_assert_not_reached() instead of assert(0)
#30: FILE: target/ppc/dfp_helper.c:141:
+ assert(0); /* cannot get here */

checkpatch is unhappy about this line:
WARNING: Block comments use a leading /* on a separate line
#50: FILE: hw/acpi/nvdimm.c:1074:
+ aml_equal(aml_sizeof(pckg), aml_int(1)) /* 1 element? */));
but there's nothing wrong with it - the check is just too simplistic. It
will also miss lines which mix inline and block comments.
Instead, let's strip all inline comments from a line and then check for block
comments.

Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.
This avoids the need for a constructor initialization too.
