8f75b6b923
Affects both utilsAppendFormattedStringToBuffer() and logWriteFormattedStringToBuffer(). Fixes logging issues within both the exception handler and memory debugging code. Other changes include: * bfttf: rename BfttfFontType_Total -> BfttfFontType_Count. * config: rename "append_authoringtool_data" -> "generate_authoringtool_data". * fs_ext: update FsGameCardCertificate struct * gamecard: fix gamecardReadLotusAsicFirmwareBlob() not returning false if FS .data segment memory couldn't be retrieved; update GameCardInfo struct to reflect a recently discovered area that's not zeroed out. * mem: expand MemoryProgramSegmentType enum; define extra macros for PID buffer size and memory page type checks; force empty memory page attribute and R/X permission checks while looking for the last FS .text segment; make memory page filtering code more readable. * npdm: rename KernelCapability enums; rename entry_value -> bitmask in all KernelCapability descriptor structs. * tik: force byte-for-byte memory lookup while dumping volatile tickets. * libs: update libusbhsfs to latest commit. * codebase: add missing comments to some enums; add missing "None" and "Count" elements to some enums. "Count" entries from enums with bitmasks will only reflect the number of available bitmask values. Enums with hex values remain unchanged. * PoC builds: use EXIT_SUCCESS and EXIT_FAILURE as return values. * nxdt_rw_poc: move "end" jump label within main() to avoid a crash if utilsInitializeResources() fails; reflect changes in config.c.
