build and tests: curl_10char_object_name() shell function

lib/objnames.inc provides definition of curl_10char_object_name() shell
function. The intended purpose of this function is to transliterate a
(*.c) source file name that may be longer than 10 characters, or not,
into a string with at most 10 characters which may be used as an OS/400
object name.

Test case 1221 does unit testng of this function and also verifies
that it is possible to generate distinct short object names for all
curl and libcurl *.c source file names.

lib/objnames-test.sh is the shell script used for test case 1221.

tests/runtests.pl modified to accept shell script test cases.

More details inside lib/objnames.inc and lib/objnames-test.sh

# curl_10char_object_name
#
# This shell function accepts a single string argument with unspecified
# length representing a (*.c) source file name and returns a string which
# is a transformation of given argument.
#
# The intended purpose of this function is to transliterate a (*.c) source
# file name that may be longer than 10 characters, or not, into a string
# with at most 10 characters which may be used as an OS/400 object name.
#
# This function might not be universally usefull, nor we care about it.
#
# It is intended to be used with libcurl's (*.c) source file names, so
# dependency on libcurl's source file naming scheme is acceptable and
# good enough for its intended use. Specifically it makes use of the fact
# that libcurl's (*.c) source file names which may be longer than 10 chars
# are conformed with underscore '_' separated substrings, or separated by
# other character which does not belong to the [0-9], [a-z] or [A-Z] sets.
#
# This allows repeatable and automatic short object name generation with
# no need for a hardcoded mapping table.
#
# Transformation is done in the following way:
#
# 1) Leading directory components are removed.
# 2) Leftmost dot character and any other char following it are removed.
# 3) Lowercase characters are transliterated to uppercase.
# 4) Characters not in [A-Z] or [0-9] are transliterated to underscore '_'.
# 5) Every sequence of one or more underscores is replaced with a single one.
# 6) Five leftmost substrings which end in an underscore character are
# replaced by the first character of each substring, while retaining
# the rest of the string.
# 7) Finally the result is truncated to 10 characters.
#
# Resulting object name may be shorter than 10 characters.
#
# Test case 1221 does unit testng of this function and also verifies
# that it is possible to generate distinct short object names for all
# curl and libcurl *.c source file names.
