4482 5469 d 20 h decky /trunk/uspace/lib/libc/ I/O subsystem overhaul:
- add more POSIX-like file and stream functions (with real functionality of stdin, stdout, stderr)
- cleanup console access methods (now generic to any console-like device)
- remove unsafe stream functions
- add special open_node(), fd_node(), fd_phone() (file) and fopen_node(), fnode(), fphone() (stream) functions for HelenOS-specific I/O operations

2570 6078 d 1 h jermar /trunk/uspace/lib/libc/generic/io/ Fix a bug in interpretation of precision when printing strings. Fix cstyle.  
2479 6181 d 2 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2230 6255 d 23 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console
 
2229 6256 d 2 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.
 
2209 6257 d 22 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
