- dce-os-worker.c/.h module exposes functionality which allows
DCE KMD clients to wait/signal events.
- The current abstraction of this module has following drawbacks
which this change attempts to address:
* Name: dce-os-worker is a misnomer
- Rename to dce-wait-cond.c/.h and make it a dce-kmd core file.
- Rename functions accordingly.
* dce-os-worker module initializes data structures from tegra_dce
which makes it ineligible for re-use.
- dce-client-ipc can re-use this module as it uses exact
same functionality.
- But this module is tied with DCE-KMD core such that it has
functions that operate on fixed known inputs.
- dce_os_work_cond_sw_resource_init/deinit()
Inits/Deinits most but not all condition var resources
from tegra_dce. Eg. dce-client-ipc resources
are not initialized.
- Move this function to new core file:dce-waiters.c
- All other functions require msg_id as input and can only
operate on DCE_WAIT* resources making it ineligible
to be used by other clients like dce-client-ipc.
- Refactor these fucntions to operate on
individual wait conditions so that all DCE-KMD
core modules can reuse them.
- Additionally, this change will also remove unused functions
and macros from dce-os-cond.c/.h
- dce-client-ipc will also switch to use dce-wait-cond interface
for client ipc waits.
- Make dce-os-cond.h a common file and move OS specific impl
to dce-os-cond-internal.h

- dce-client-ipc.c has linux specific export symbols that
are required to be exported to linux kernel module client.
- We'll be using dce-client-ipc.c as a core DCE-KMD file and
also be compiling it for HVRTOS.
- This change will add DCE_EXPORT_SYMBOL() as wrapper
to EXPORT_SYMBOL. This will be OS agnostic macro.
- For HVRTOS it will be empty.

- This change will remove linux nuances from dce-client-ipc.c
file and make it a core DCE-KMD file agnostic to OS.
- To do that, dce-client-ipc module will repalce linux specific
nuances for work queue related functionality with
dce-os-work module.
- Further to support existing dce_client_ipc asyn callback function
we need to make worker queue more generic by allowing clients
to pass any data of their choice as data param to the
callback function.
- Also take this opportunity to make following functions static:
- dce_resume_work_fn()
- dce_bootstrap_work_fn()

- This is pre-req to make dce-client-ipc.c a core file and use
it for HVRTOS as well.
- dce-client-ipc.c uses worker queues today to manage async events.
But instead of using existing dce-os-work abstraction it
directly uses linux structs/calls.
- Current dce-os-work abstraction cannot be used as is for
dce-client-ipc.c as it only allows scheduling work
to system hipri work queue. But dce-client-ipc creates
and schedules work to a new worker queue.
- To allow dce-client-ipc.c use exising dce-os-work abstraction,
we need to make it more generic such that work can be scheduled
either to a new queue or existing system hipri work queue.
- This CL will update worker queue abstraction to make it more generic
and start using it for usecases which use default sys hipri WQ.
- There will be a follow-up CL for dce-client-ipc to start using
this abstraction.
- Further, this change will also make WQ and work structs
opaque and make dce-os-work.h a common header.

- Rename dce-os-device to dce-linux-device
- dce-os-device.h header is specific to OS and is only intended
to be internally used within OS. Similarly all it's exposed
functions are OS specific only.
- Therefore instead of having a common name for all OSs for this
header file, make this header internal by including linux
name to it's naming convention.
- Similary rename dce_os_device struct to dce_linux_device and
also rename corresponding functions from this header.

- Abstract out iosys_* dependencies for writing/reading to/from
message header and memcpy to os specific implementation.
- Add new dce-os-ipc.c
- Cannot add these functions to existing 'dce-os-ivc.h' as
static inline functions because these functions access
dce_ipc_channel defined in dce_ipc.h.
- Cannot include dce_ipc.h to this file as it creates
a circular dependency.
- Also fix exsisting issue of not defining 'tegra_dce' inside
dce-ipc.h
- This is exposed now because we're including dce-ipc.h to
dce-os-ipc.c which doesn't include any prior headers which
define tegra_dce.
- Fix by doing forward define to avoid circular dependency
with dce.h
- Additionally fix below iosys issues:
1) Change Iabebef33719c38a8aa4db8573a0dd7dd7e5f83f6 introduced
an issue because NV_TEGRA_IVC_STRUCT_HAS_IOSYS_MAP demands
different prototypes for below functions:
- dce_os_ivc_get_next_write_frame()
- dce_os_ivc_get_next_read_frame()
2) Now since dce_ipc_is_data_available() uses
dce_os_ivc_get_next_read_frame(), it needs to define
frame with iosys_map for IOSYS Linux 6.2 usecase. So need
to creata a OS abstraction for this too.

- This change will add new DCE OS interface for types.h.
- This DCE OS interface layer will act as entry point to OS layer
from core DCE-KMD code.
- The intended usage is as follows.
- DCE-KMD core will include respective OS header file from
DCE OS interface.
Eg. In dce-fsm.c
#include <dce-os-types.h>
- DCE OS interface will further include OS specific files
Eg. In dce-os-types.h
#include <os-types.h>
- OS specific files will reside in respective OS specific paths.
Eg. for Linux the path will be
kernel/nvidia-oot/../dce/os/include/linux/os-types.h
For HVRTOS the path will be
display/server/os/include/hvrtos/os-types.h
- The OS specific paths will be directly included in respective
OS makefiles during compilation so that we don't need to use
ifdefs within DCE OS interface layer.
- This is first change to follow this convention for types.h.
We will have follow-up CLs to follow this suite for all other
OS dependencies for DCE-KMD.

- From that copy, only linux-kmd relevant headers
are mirrored here as there's no need to mirror HVRTOS

- But we need a copy here as we cannot include external paths
