Macros
#define	CBPRINTF_PACKAGE_ALIGNMENT
	Required alignment of the buffer used for packaging.
#define	CBPRINTF_PACKAGE_CONST_CHAR_RO   BIT(0)
	Assume that const char pointer is pointing to read only (constant) strings.
#define	CBPRINTF_PACKAGE_ADD_RO_STR_POS   BIT(1)
	Append locations (within the package) of read-only string pointers.
#define	CBPRINTF_PACKAGE_ADD_RW_STR_POS   BIT(2)
	Append locations (within the package) of read-write string pointers.
#define	CBPRINTF_PACKAGE_FIRST_RO_STR_CNT(n)
	Indicate that n first string format arguments are char pointers to read-only location.
#define	CBPRINTF_PACKAGE_ADD_STRING_IDXS    (CBPRINTF_PACKAGE_ADD_RO_STR_POS | CBPRINTF_PACKAGE_CONST_CHAR_RO)
	Append indexes of read-only string arguments in the package.

	Append read-only strings from source package to destination package.
#define	CBPRINTF_PACKAGE_CONVERT_RW_STR   BIT(1)
	Append read-write strings from source package to destination package.
#define	CBPRINTF_PACKAGE_CONVERT_KEEP_RO_STR   BIT(2)
	Keep read-only location indexes in the package.
#define	CBPRINTF_PACKAGE_CONVERT_PTR_CHECK   BIT(3)
	Check format string if p argument was treated as s in the package.
#define	CBPRINTF_MUST_RUNTIME_PACKAGE(flags, ...)
	Determine if string must be packaged in run time.
#define	CBPRINTF_STATIC_PACKAGE(packaged, inlen, outlen, align_offset, flags, ...)
	Statically package string.
