read readme_lp9lib in 9lau/src

2023/07/09
clean up and update

2023/07/28
- Added p9.getpid()

2023/10/01
- fixed mkfile 
	lua/src/mkfile
	9lua/src/mkfile
to make integer in Lua to be 64bit type
NB: f:seek("set",n) does not work for large n ( larger than 2^31 )
NB: /amd64/include/ape/math.h is buggy. they does not include
	extern double log2(double);
another solusion (maybe a better solusion) suggested by Amavect:
	remove /amd64/include/ape/math.h
- added 
	extern int getpid(void);
in 9lua/src/lp9lib.c

2023/10/06
- fixed mkfile and luaconf.h
	lua/src/mkfile
	9lua/src/mkfile
	lua/src/luaconf.h
	9lua/src/luaconf.h
to make seek over 2^31
and now io.popen(cmd) works.
