Hi folks!

Finally, I decided to submit my patch, which makes SystemTap work for
Android. Moreover, it adds two new features:
- Support for ignoring all available tapset directories, except the one
that is provided by -K
- Support for a pid file in staprun, parameter is -U
I had to modify several source files of staprun. Those changes are
mostly copied from the corresponding files contained in commit
2c10863bfe41b51272eff714a837f4977bdc257a. For some reasons, those ifdef
parts have been removed. I readded them, and changed the macro, which
activates them.

The patch contains two bugfixes for the SystemTap as well.
Unfortunately, I failed to extract those fixes properly. :(
The first fix starts at line 510, and goes until line 555.
Since an older kernel like 3.0 does not support uprobes, systemtap
includes 'runtime/linux/task_finder_stubs.c'. That file itself does
*not* include 'syscall.h', which declares several syscall-related functions.
The second fix starts at line 1106. For some reasons in the Linux kernel
3.0 the macro cputime_to_usecs() has a semicolon at the end of its
definition. Therefore, the defition of cputime_to_msecs() in '
tapset/linux/task_time.stp' must be modified to deal with that fact.

Cheers,
Alex
