add new package: redir (#772) * add bvi package * add new package: cgdb * add gdb in cgdb's TERMUX_PKG_DEPENDS * add new package: redir * bvi package revision 1: fix column number issue with clang (gcc does not seem to have this issue) bvi (compiled with clang) incorrectly displayed only 12 bytes for each line on a 80-column terminal (instead of 16 bytes normally). command :set cm=## also had similar problems. I found the issue was caused by the following statements: sprintf(addr_form, "%%0%dllX ", AnzAdd); AnzAdd = sprintf(tmp, addr_form, block_begin); ('block_begin''s data type is off_t) gcc automatically typecasts 'block_begin' from off_t to loff_t, on the otherhand, clang takes address of 'block_begin' and uses it as loff_t thus writes some garbage value in 'tmp' string. 2017-02-20 22:14:52 +01:00			`--- bvi-1.4.0/bm_unix.c 2013-08-25 11:59:33.000000000 -0700`
