search_pattern_in_file.inc changes

Browse Source 
1. Special mode to search in error logs: if SEARCH_RANGE is not set,
   the file is considered an error log and the search is performed
   since the last CURRENT_TEST: line
2. Number of matches is printed too. "FOUND 5 /foo/ in bar".
   Use greedy .* at the end of the pattern if number of matches
   isn't stable. If nothing is found it's still "NOT FOUND",
   not "FOUND 0".
3. SEARCH_ABORT specifies the prefix of the output.
   Can be "NOT FOUND" or "FOUND" as before,
   but also "FOUND 5 " if needed.

# Optionally, SEARCH_RANGE can be set to the max number of bytes of the file
# to search. If negative, it will search that many bytes at the end of the
# file. The default is to search only the first 50000 bytes of the file.
# file. By default the search happens from the last CURRENT_TEST:
# marker till the end of file (appropriate for searching error logs).
#
# Optionally, SEARCH_ABORT can be set to "FOUND" or "NOT FOUND" and this
# will abort if the search result doesn't match the requested one.
#
# In case of
# - SEARCH_FILE and/or SEARCH_PATTERN is not set
# - SEARCH_FILE cannot be opened
# - SEARCH_FILE does not contain SEARCH_PATTERN
# the test will abort immediate.
# MTR will report something like
# ....
