dtoa() is buggy. The bug would cause incorrect output to be
generated when format strings such as '%5.0f' were used with
nonzero numbers whose magnitude is less than 1.

Data type corrections:
- Define a variable which contains a file byte offset value as type
off_t as required by the `crc' function.

`crc_total' is defined as an `uint32_t', thus fixing

- Change linux_get_prison() to take a thread instead of a proc for its
first argument and to use td_ucred rather than p_ucred. This is ok
because a thread's prison does not change even though it's ucred might.
- Also, change linux_get_prison() to return a struct prison * instead of
a struct linux_prison * since it returns with the struct prison locked
and this makes it easier to safely unlock the prison when we are done
messing with it.
KTR_DROP set in its header, then we output an extra line to stdout to
indicate that events were dropped between the previous record and this
record. It is a bit trickier because we need to always notify the user
if events are dropped even if KTR_DROP is set on a record of a type that
we aren't interested in since kdump(8) doesn't know if the dropped events
were of the types that the user has requested. To avoid outputting
multiple events dropped notices in between actual event logs, a state
variable is set whenever a drop is logged and cleared whenever an actual
record is output.

KTRFAC_DROP to track instances when ktrace events are dropped due to the
request pool being exhausted. When a thread tries to post a ktrace event
and is unable to due to no available ktrace request objects, it sets
KTRFAC_DROP in its process' p_traceflag field. The next trace event to
successfully post from that process will set the KTR_DROP flag in the
header of the request going out and clear KTRFAC_DROP.
The KTR_DROP flag is the high bit in the type field of the ktr_header
structure. Older kdump binaries will simply complain about an unknown type
when seeing an entry with KTR_DROP set. Note that KTR_DROP being set on a
record in a ktrace file does not tell you anything except that at least one
event from this process was dropped prior to this event. The user has no
way of knowing what types of events were dropped nor how many were dropped.

struct proc as p_tracecred alongside the current cache of the vnode in
p_tracep. This credential is then used for all later ktrace operations on
this file rather than using the credential of the current thread at the
time of each ktrace event.
- Now that we have multiple ktrace-related items in struct proc that are
pointers, rename p_tracep to p_tracevp to make it less ambiguous.

frames. A comment in if_atm.h suggests that both macros, that for extracting
the ethertype and that for inserting it, handle their argument in host
byte order. In fact, the inserting macro treated its argument as an opposite
host order short and the calling code feeds it the result of htons(). This
happens to work on i386, but fails on sparc. Make the macro use real host
endianess.
