MDEV-35350: Backport search_pattern_in_file.inc for SEARCH_WAIT functionality

Browse Source 
For easier diff comparison, this commit takes
search_pattern_in_file.inc from 10.11 as-is for the
SEARCH_WAIT functionality added by Kristian Nielsen.
The changes to make it replace
wait_for_pattern_in_file.inc are in the following
commit.

Note that this commit breaks existing
wait_for_pattern_in_file.inc usage, so any tests which
use it will fail if building here.

# 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.
#
# Optionally, SEARCH_ABORT_IS_SUCCESS can be set to inverse the error logic
# when the SEARCH_ABORT condition is met. The specific cases and behaviors
# become:
#
# 1) In the normal case (SEARCH_ABORT_IS_SUCCESS is NOT set), when the
# matching result (FOUND N or NOT FOUND) matches SEARCH_ABORT, exit in
# error (via die); otherwise, we assume success and print the matching
# result. This is used in the normal search_pattern_in_file.inc case,
# as well as wait_for_pattern_in_file.inc when searching that some
# pattern exists at all (i.e. a result of NOT FOUND will trigger die,
# so the script can continue waiting until the result is found, and
# finally print the result).
#
# 2) If SEARCH_ABORT_IS_SUCCESS is set, then we want to inverse the logic
# from case (1). That is, if the match result is SEARCH_ABORT, this
# is the success case, and we die for all other matching results.
# Optionally, SEARCH_WAIT can be set to "FOUND" or "NOT FOUND", and this
# will wait for the condition to occur. The timeout can be set in
# SEARCH_TIMEOUT, default is 60 seconds.
#
# Optionally, SEARCH_OUTPUT can be set to control the format of output.
# Supported formats:
# - (default) : "FOUND n /pattern/ in FILE " or "NOT FOUND ..."
# - "matches" : Each match is printed, on a separate line
# - "count" : "FOUND n matches in FILE" or "NOT FOUND ..." (omit pattern)
#
# In case of
# - SEARCH_FILE and/or SEARCH_PATTERN is not set
