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libtraceevent is now out-of-date and it is better to depend on the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.

-DESCRIPTION
------------
-These functions print recorded field's data, according to the field's type.
-
-The _tep_print_field()_ function extracts from the recorded raw _data_ value of
-the _field_ and prints it into _s_, according to the field type.
-
-The _tep_print_fields()_ prints each field name followed by the record's field
-value according to the field's type:
-[verse]
---
-"field1_name=field1_value field2_name=field2_value ..."
---
-It iterates all fields of the _event_, and calls _tep_print_field()_ for each of
-them.
-
-The _tep_print_num_field()_ function prints a numeric field with given format
-string. A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_ and is printed in the
-_s_, according to the given format string _fmt_. If the argument _err_ is
-non-zero, and an error occures - it is printed in the _s_.
-
-The _tep_print_func_field()_ function prints a function field with given format
-string.  A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_. The value is assumed
-to be a function address, and a search is perform to find the name of this
-function. The function name (if found) and its address are printed in the _s_,
-according to the given format string _fmt_. If the argument _err_ is non-zero,
-and an error occures - it is printed in _s_.
-
-RETURN VALUE
-------------
-The _tep_print_num_field()_ and _tep_print_func_field()_ functions return 1
-on success, -1 in case of an error or 0 if the print buffer _s_ is full.

-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-#include <trace-seq.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-struct trace_seq seq;
-trace_seq_init(&seq);
-struct tep_event *event = tep_find_event_by_name(tep, "timer", "hrtimer_start");
-...
-void process_record(struct tep_record *record)
-{
-	struct tep_format_field *field_pid = tep_find_common_field(event, "common_pid");
-
-	trace_seq_reset(&seq);
-
-	/* Print the value of "common_pid" */
-	tep_print_field(&seq, record->data, field_pid);
-
-	/* Print all fields of the "hrtimer_start" event */
-	tep_print_fields(&seq, record->data, record->size, event);
-
-	/* Print the value of "expires" field with custom format string */
-	tep_print_num_field(&seq, " timer expires in %llu ", event, "expires", record, 0);
-
-	/* Print the address and the name of "function" field with custom format string */
-	tep_print_func_field(&seq, " timer function is %s ", event, "function", record, 0);
- }

-*event-parse.h*
-	Header file to include in order to have access to the library APIs.
-*trace-seq.h*
-	Header file to include in order to have access to trace sequences related APIs.
-	Trace sequences are used to allow a function to call several other functions
-	to create a string of data to use.
-*-ltraceevent*
-	Linker switch to add when building a program that uses the library.
