Every exported buffer transform now has the same shape:
int32_t AARU_xxx(const uint8_t *src_buffer, size_t src_size,
uint8_t *dst_buffer, size_t *dst_size, ...extras);
On entry *dst_size is the capacity of dst_buffer; on success it holds the
number of bytes written. The return value is 0 (AARU_ERROR_NONE) on success
and non-zero on error, either an AARU_ERROR_* constant or the underlying
library's own error code when it is propagated.
Changes by category:
- Parameter reorder only: all AARU_zip_*, AARU_stuffit*, AARU_dd_*,
AARU_cpt_*, AARU_lzo_*, AARU_xz_*, AARU_lzma2_*, AARU_kencode_*,
AARU_apple_lzh_* and ace_decompress_*.
- Byte count return replaced by an out-parameter plus a status code:
AARU_adc_*, AARU_apple_rle_*, AARU_lz4_*, AARU_lzip_*, AARU_lzfse_*,
AARU_lzvn_*, AARU_zstd_* and AARU_flac_*. Their algorithm bodies are kept
as static internals behind a thin exported wrapper.
- Type normalisation: bzip2 uint32_t* -> size_t*, zstd void* -> uint8_t*,
ZIP PPMd size_t -> size_t*, and int/unsigned char -> int32_t/uint8_t
throughout the header.
- AARU_lzma_decode_buffer no longer takes src_size as an in/out pointer; the
consumed length is tracked internally.
- Already conforming decompressors (arc_*, pak_*, ha_*, lha_*, larc_*,
pmarc_*, arj*, rar*, lh5_decompress) only had their declarations
normalised.
The streaming LZD context API and AARU_get_acn_version are left alone, as
they are not buffer transforms.
Tests updated to the new call convention; all 78 pass.
