2017-01-09Allow 'gzip -d' and 'bzip2 -d' without gunzip or bunzip2Kang-Che Sung

2017-01-08bunzip2: fix code bloat caused by zcat's seamless magicKang-Che Sung
This example single-applet configuration would trigger the bloat: CONFIG_FEATURE_SEAMLESS_XZ=y CONFIG_FEATURE_SEAMLESS_LZMA=y CONFIG_FEATURE_SEAMLESS_BZ2=y CONFIG_FEATURE_SEAMLESS_GZ=y CONFIG_BUNZIP2=y # CONFIG_ZCAT is not set # All other applets disabled Here, the resulting "busybox-bunzip2" binary would contain unpack_gz_stream, unpack_lzma_stream and unpack_xz_stream functions code. In other words, the gzip, lzma and xz decompressors' code are linked into the binary unnecessarily. This happens because SEAMLESS_MAGIC != 0 and compiler is unable to figure out that SEAMLESS_MAGIC bit is never set. Fix this by disabling SEAMLESS_MAGIC option flag (setting its value to 0) when zcat is disabled. This will help the compiler optimize out bbunpack() and no longer generate open_zipped() function call.

2016-08-15gzip: fix compression level bug. Closes 9131Natanael Copa
fix broken logic to get the gzip_level_config value from options -1 to -9. This fixes an off-by-one bug that caused gzip -9 output bigger files than the other compression levels. It fixes so that compression level 1 to 3 are actually mapped to level 4 as comments say. It also fixes that levels -4 to -9 is mapped to correct level and avoids out-of-bounds access.
