+ api: rewrote almost everything from scratch. tnx Ken Lalonde for
+ suggesting mmap.
+20000216
+ ui: cdbget supports skip.
+ version: cdb 0.70, beta.
+20000219
+ bug: cdb_make_addbegin() didn't explicitly return 0. impact:
+ database creation could fail on systems that didn't
+ follow the traditional C return behavior. fix: obvious.
+ tnx Uwe Ohse.
+ internal: increased bspace in cdb_make.h from 1024 to 8192.
+ internal: switched cdbmake to PUTC, GETC. 3x speedup here.
+ internal: added testzero to rts.
+ ui: posplus() sets nomem if it passes 4GB.
+ version: cdb 0.75, beta.
