53c8faaafc LibCore: Trim trailing whitespaces from ConfigFile values
Previously, trailing whitespaces were not removed from values in
config files. This could cause errors with poorly formatted files.
This commit fixes this by trimming whitespaces from values in
ConfigFile::reparse().

b3e9a4e603 Libraries: Fix visibility of Object-derivative constructors
Derivatives of Core::Object should be constructed through
ClassName::construct(), to avoid handling ref-counted objects with
refcount zero. Fixing the visibility means that misuses like this are
more difficult.

2e6bb987a3 AK+WindowServer: Remove did_construct() framework used only once
There is also make_ref_counted(), which does not call did_construct(),
so the method was not guaranteed to be run. Since there is only a single
user, and `WindowServer::Window` is a final class anyway (so there is no
need to separate the constructor and post-constructor phases), let's get
rid of this concept.

(The following commits reduce the opportunities to call
make_ref_counted, but still.)

ObjectClassRegistration's construct() method will always return null.

ea9f2f80a1 LibCore: Make ArgsParser '--help' description more general

the help message should no longer be self-referential.

0372f051e9 LibCore: Enable emitting markdown from ArgsParser
ArgsParser will now automatically look for an environment variable
'ARGSPARSER_EMIT_MARKDOWN', and if it is set to exactly the string "1"
(i.e. mere presence or values like "ON" or "yes" are not enough), then
ArgsParser will emit a Markdown-formatted help message, instead of the
regular help message designed for consumption through a terminal.

232f54cd9b LibCore: Fix off-by-one in DateTime::{create,set_time} day default arg
Just like month, the day value here is one-based. This resulted in the
following situation, which is obviously unexpected:

    Core::DateTime::create(1970); // 1970-01-00 -> 1969-12-31

when file size is needed without having to open the file to query it

fa753ff863 LibCore: Pop the main Core::EventLoop off the stack when destroyed
The main event loop pushes itself onto the event loop stack, and so it
should also pop itself when destroyed.

This will surface attempts to use the event loop stack after the main
event loop has been destroyed.

204a091765 LibCore: Avoid buffer overrun when invoking crypt() with a SecretString
For example, consider the following SecretString construction:

    String foo = "foo";
    auto ss = SecretString::take_ownership(foo.to_byte_buffer());

The ByteBuffer created by to_byte_buffer() will not contain the NUL
terminator. Therefore, the value returned by SecretString::characters
will not be NUL-terminated either.

Currently, the only use of SecretString is to pass its character data to
crypt(), which requires a NUL-terminated string. To ensure this cannot
result in a buffer overrun, make SecretString append a NUL terminator to
its buffer if there isn't one already.

4739982c66 LibCore: Change Account::set_password to take a SecretString
This matches the API of Account::authenticate. The only caller to this
API is the passwd utility, which already has the new password stored as
a SecretString.

29acb7fcf8 LibCore: Add a Socket::set_idle() API that turns the notifiers on/off
When a socket's user doesn't need it to be active, but wants to keep it
open, the socket's notifiers should not be enabled to avoid hogging the
CPU with effectively useless notifications.
This API can be used to disable said notifiers until the user needs the
notifications.

e112e6620f LibCore: Allow reads smaller than the buffered data size in IODevice
This restriction doesn't make much sense, a user should be free to
consume the buffered data with as small a max_size as they desire.
This fixes a possible RequestServer spin when talking to HTTP servers.

b0a9c5673e LibHTTP: Respect the 'Connection: close' header on keep-alive jobs
If the server responds with this header, we _must_ close the connection,
as the server is allowed to ignore the socket and not respond to
anything past that response.
Fixes some RequestServer spins.

484f6a7cfa LibCore: Buffer small byte reads
Prior this change, if you had a program which frequently reads small
amount of bytes, then it would constantly fire up syscalls.

This patch sets that the minimum size that is passed to the read syscall
is 1024 and then it saves these additional bytes in a buffer for next
reads, which greatly improves the cpu usage on such cases.

In other words: reading flacs is now very efficient.

bd4f7421cf LibCore: Don't double-check select() in Socket's read notifier callback
This was used to work around a possible bug where select() would mark a
socket readable, but another user of the same socket would read before
the notifier's callback is run; let's remove this and fix any issues
regarding that specific situation later when they pop up.

65f7e45a75 RequestServer+LibHTTP+LibGemini: Cache connections to the same host
This makes connections (particularly TLS-based ones) do the handshaking
stuff only once.
Currently the cache is configured to keep at most two connections evenly
balanced in queue size, and with a grace period of 10s after the last
queued job has finished (after which the connection will be dropped).

9e667453c7 LibCore: Make get_password return SecretString instead of String

3bf6902790 LibCore: Add SecretString, a buffer that is zero'd on destruction
We have a few places where we read secrets into memory, and then
do some computation on them. In these cases we should always make
sure we zero the allocations before they are free'd.

The SecureString wrapper provides this abstraction by wrapping a
ByteBuffer and calling explicit_bzero on destruction of the object.

fd3735199b LibCore: Fix link_file inverting src and dst paths on duplicate names
File::link_file takes the dst_path then the src_path so on duplicate
names we tried to create a link at the original file location, which
then flipped the parameters back round again and we ended up with a
broken link from "dst_path (1)" to "src_path (1)".

2e4ec891da Everywhere: Fix format-vulnerabilities
Command used:
grep -Pirn '(out|warn)ln\((?!["\)]|format,|stderr,|stdout,|output, ")' \
     AK Kernel/ Tests/ Userland/
(Plus some manual reviewing.)

Let's pick ArgsParser as an example:
    outln(file, m_general_help);
This will fail at runtime if the general help happens to contain braces.

Even if this transformation turns out to be unnecessary in a place or
two, this way the code is "more obviously" correct.
