Since clear_bit is an atomic operation, the spinlock is redundant and
can be removed, reducing lock contention is good for performance.

This patch adds SIOCINQ ioctl tests for both SOCK_STREAM and
SOCK_SEQPACKET.
The client waits for the server to send data, and checks if the SIOCINQ
ioctl value matches the data size. After consuming the data, the client
checks if the SIOCINQ value is 0.

The value of the SIOCINQ is obtained by `virtio_transport_unread_bytes()`,

Similar with SIOCOUTQ ioctl, the information is transport-dependent.

The function stubs exposed by module.h allow the code to compile properly
without the ifdeffery. The generated object code stays the same, as the
compiler can optimize away all the dead code.
As the code is still typechecked developer errors can be detected faster.

I investigated the history for a bit and it
The struct was moved to the public header file in
commit c8e21ced08b3 ("module: fix kdb's illicit use of struct module_use.").
Back then the structure was used outside of the module core.
Nowadays this is not true anymore, so the structure can be made internal.

To write code that works with both CONFIG_MODULES=y and CONFIG_MODULES=n
it is convenient to use "if (IS_ENABLED(CONFIG_MODULES))" over raw #ifdef.
The code will still fully typechecked but the unreachable parts are
discarded by the compiler. This prevents accidental breakage when a certain
kconfig
Code using IS_ENABLED(CONFIG_MODULES) as a C expression may need access
to the module structure definitions to compile.
Make sure these structure definitions are always visible.

When we add parameter support to the module macro, we want to be able to
pass a reference to `ModuleInfo` to a helper function. That is not possible
when we move out of the local `modinfo`. So change the function to access
the local via reference rather than value.

Extend the `module!` macro with support module parameters. Also add some string
to integer parsing functions and updates `BStr` with a method to strip a string
prefix.
Based on code by Adam Bratschi-Kaye lifted from the original `rust` branch [1].
