tools lib traceevent: Remove libtraceevent

libtraceevent is now out-of-date and it is better to depend on the
system version. Remove this code that is no longer depended upon by
any builds.

Committer notes:

Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so
that 'make perf-tar-src-pkg' works.

-NAME
-----
-tep_print_event - Writes event information into a trace sequence.
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-*#include <trace-seq.h>*
-
-void *tep_print_event*(struct tep_handle pass:[*]_tep_, struct trace_seqpass:[*]_s_, struct tep_record pass:[*]_record_, const char pass:[*]_fmt_, _..._)
---

-DESCRIPTION
------------
-
-The _tep_print_event()_ function parses the event information of the given
-_record_ and writes it into the trace sequence _s_, according to the format
-string _fmt_. The desired information is specified after the format string.
-The _fmt_ is printf-like format string, following arguments are supported:
-[verse]
---
-	TEP_PRINT_PID, "%d"  - PID of the event.
-	TEP_PRINT_CPU, "%d"  - Event CPU.
-	TEP_PRINT_COMM, "%s" - Event command string.
-	TEP_PRINT_NAME, "%s" - Event name.
-	TEP_PRINT_LATENCY, "%s" - Latency of the event. It prints 4 or more
-			fields - interrupt state, scheduling state,
-			current context, and preemption count.
-			Field 1 is the interrupt enabled state:
-				d : Interrupts are disabled
-				. : Interrupts are enabled
-				X : The architecture does not support this
-				    information
-			Field 2 is the "need resched" state.
-				N : The task is set to call the scheduler when
-				    possible, as another higher priority task
-				    may need to be scheduled in.
-				. : The task is not set to call the scheduler.
-			Field 3 is the context state.
-				. : Normal context
-				s : Soft interrupt context
-				h : Hard interrupt context
-				H : Hard interrupt context which triggered
-				    during soft interrupt context.
-				z : NMI context
-				Z : NMI context which triggered during hard
-				    interrupt context
-			Field 4 is the preemption count.
-				. : The preempt count is zero.
-			On preemptible kernels (where the task can be scheduled
-			out in arbitrary locations while in kernel context), the
-			preempt count, when non zero, will prevent the kernel
-			from scheduling out the current task. The preempt count
-			number is displayed when it is not zero.
-			Depending on the kernel, it may show other fields
-			(lock depth, or migration disabled, which are unique to
-			specialized kernels).
-	TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be
-			specified as part of this format string:
-			"%precision.divisord". Example:
-			"%3.1000d" - divide the time by 1000 and print the first
-			3 digits before the dot. Thus, the time stamp
-			"123456000" will be printed as "123.456"
-	TEP_PRINT_INFO, "%s" - event information.
-	TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

-void print_my_event(struct tep_record *record)
-{
-	trace_seq_reset(&seq);
-	tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s",
-			TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU,
-			TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME,
-			TEP_PRINT_INFO);
