Stat "/proc/<pid>" instead of "/proc/<pid>/state" to get uid' and gid'.

1999-11-28  Martin Baulig  <martin@home-of-linux.org>

	* procstate.c (glibtop_get_procstate_s): Stat "/proc/<pid>" instead
	of "/proc/<pid>/state" to get `uid' and `gid'. Thanks to Jason Becker
	for pointing out that GTop reported wrong uid's.

* ------------------------------------------------------------
* This is from the manpage of isdninfo(4):
*
* DESCRIPTION
* /dev/isdninfo is a character device with major number 45
* and minor number 255. It delivers status information from
* the Linux ISDN subsystem to user level.
*
* DATA FORMAT
* When reading from this device, the current status of the
* Linux ISDN subsystem is delivered in 6 lines of text. Each
* line starts with a tag string followed by a colon and
* whitespace. After that the status values are appended sep-
* arated by whitespace.
*
* flags is the tag of line 5. In this line for every driver
* slot, it's B-Channel status is shown. If no driver
* is registered in a slot, a ? is shown. For every
* established B-Channel of the driver, a bit is set
* in the shown value. The driver's first channel is
* mapped to bit 0, the second channel to bit 1 and so
* on.
* ------------------------------------------------------------
*
* So we open /dev/isdninfo, discard the first four lines of text
* and then check whether we have something that is not `0' or `?'
* in one of the flags fields.
*
* Sounds complicated, but I don't see any other way to check whether
* we are connected. Also, this is the method some other ISDN tools
* for Linux use.
*
* Martin
