Add supllementary explainations for q_ascend and q_descend,
indicating the required memory operations that must be
implemented in these functions.

The original comment states that false is returned when list head is
NULL. However, this is inconsistent with functions such as
'q_delete_mid' and has been confirmed to be a typo.

This commit introduces a generic alloc function to handle both
test_malloc and test_calloc operations based on the provided
alloc_func_t. Additionally, it implements the test_calloc function to
allocate memory and initialize it to zero.

"qcontext_t" in the description of q_merge should be queue_contex_t.

Enforce newline at the end of files

Ensure that all the files conform to the standard of having a newline
character at the end.

Integrate linenoise with web server

In the previous version of console implementation, we tried to integrate
tiny-web-server to enable the ability of processing commands from web
requests. As the result, the package linenoise which is responsible for
command-line auto-complete needs to be disabled during the running time
of tiny-web-server. Because the main loop in "line_edit()" function in
linenoise doesn't have the ability to handle web requests correctly.

When we start the web server, we use "cmd_select" in console.c and use
"select" function to monitor web socket file descriptor and stdin_fd at
the same time. I re-design the control flow of web request and
command-line input by implement the function "web_eventmux()", and
register it as a hook function of type "line_eventmux_callback_t"
inside linenoise package. As the result, we can utilize function inside
 the main loop of linenoise which is located inside the function
"line_edit()".

"web_eventmux()" is a function which use the function "select()" to
monitor both input file descriptor and web file descriptor and modify
"line_edit()" to use "eventmux_callback()" so we can process
command-line input as normal and provide the command-line auto-complete
feature alongside with the abitlity to deal with inputs from different
input sources, such as web request.

One may wonder why don't we simply modify the function "line_edit()",
the reason is that linenoise is an upstream package so we only want to
do the miminal changes to this package.

Suppress Cppcheck checking level

Refine the pre-commit hook to enforce a minimum Cppcheck version of
1.90, alerting users with an error message and providing guidance on
compiling Cppcheck from source if their version is outdated.

Additionally, upgrade the hook for "--check-level=exhaustive" option
against Cppcheck versions 2.11 and above, ensuring a comprehensive
analysis. This adjustment leverages the enhanced capabilities
available from version 2.11, promoting more detailed code quality
checks.

This commit is aiming for fixing commit #3aa0d557's misinformed title.
We just add comments to explain why this changes.

Correct function parameter to match implementation

This commit ensures that the parameters of the q_free function in
'queue.h' match those in 'queue.c'.

Fix pre-push.hook validation bug

We utilize ./scripts/pre-push.hook to do the checking when trying to do
`git push`. One of the stages is to check a speicific commit hash number
for validation of the repository.

It tries to get the hash number of commit
3ed17237, using a filter to get the
value of `commit` whose git log message matches the pattern specified
 in line 15 of `/scripts/pre-push.hook`.
However when merging the commit into the master branch, it generated a
new commit which is 390ade9e, so the
value of `commit` in line 15 of `/scripts/pre-push.hook` will be
incorrect.

That's why we modify a small part of the command in line 15 from `-n 1`
to `--skip 1`, so we can neglect the merging commit and get the actual
commit hash number we want.

Fix #151

Bump copyright year

Since the copyright date was changed, we have to adjust the range to
make git hook work again.

Enforce newline at end of files

The egrep command has been deprecated since 2007. Beginning with GNU
grep 3.8, calling the command will now issue a warning to the user that
instead they should use 'grep -E'.

Revert "Fix duplicate item detection issue"

Fix duplicate item detection issue

Remove the 'is_this_dup' from qtest.c's delete duplicate implementation.

Previously, 'is_this_dup' was used to indicate if the current item in the old list was a duplicate of the previous item, while 'is_next_dup' indicated if the current item was a duplicate of the next item.

This led to comparisons always skipping when (is_next_dup || is_this_dup) was true, resulting in the item with duplicates not being compared with items in the new list.

The 'is_next_dup' is retained for accurate comparison.

Replace numeric value with IPPROTO_TCP constant

Fix typo

Change CHUNK_SIZE to 2

CHUNK_SIZE should be 2 because the random number ranging from 0 to 65535 takes 16 bits, which is 2 bytes.
