In qdf_mem_malloc() and qdf_mem_malloc_atomic(), pass function
name and line number, and log the same in case of failure, this
approach helps to remove error logs in caller function there by
reducing text segment.

As WIN has multiple modules and QDF is the last one to be unloaded,
QDF is crashing when it tried to print the file name of an nbuf
allocated by other modules. To fix this, copy the file name in the
QDF nbuf tracker, rather than using the pointer to file name,
to avoid access to the invalid pointer.

In low memory environments using GFP_KERNEL flag may cause
scheduler thread to sleep. Scheduler thread callback handlers
are expected to be atomic in nature to ensure timely execution
of different commands. Move all allocations done by scan module
in scheduler thread context to atomic allocation.

Add QDF APIs for DMA buffer allocation and sharing with SMMU
Stage 1 translation support. When SMMU Stage 1 is enabled,
DMA APIs return IO virtual address(IOVA) instead of physical
address. This IOVA needs to be mapped to physical address by
external module before accessing these buffers.

In order to migrate existing qdf_str_* APIs to qdf_str.h from
qdf_mem.h, qdf_mem.h included qdf_str.h. Now that consumers are
including qdf_str.h directly, remove this include.

strcmp() is regularly used to compare two strings for equality. However,
reading source code using strcmp in this manner can be prone to errors
because the return values are not obvious from the function's name. In
the best case, this leads to referring to the strcmp documentation more
often than one would like. In the worst case, this leads to difficult to
spot bugs. Add a thin wrapper for this use case to make intentions
abundantly clear to future readers. This wrapper is effectively sugar
for 'strcmp(left, right) == 0'.
For example:
if (!strcmp(left, right))
/* reads: if not string compare: left, right */
Becomes:
if (qdf_str_eq(left, right))
/* reads: if string equal: left, right */

Currently, the detected memory leaks would not dump
the caller of the function which is leaking the memory.
Add an extra parameter to the table to store the caller
address and print the function during an assert.

When memory debugging is enabled, qdf_mem_malloc and qdf_mem_free do a
number of memory corruption checks. Extract these checks into their own
functions to allow other memory allocation/free logic to leverage the
same logic.

In order to support memory leak detection during a specific period of
time, add APIs to allow setting the current memory domain. Each
allocation is tracked against the current memory domain at the time of
allocation. Consumers can then check to ensure the memory domain is
empty before each transition to a different domain.

Do following cleanup on fastpath code changes:
1) Do not reap off Tx HIF buffers in Rx handling, instead handle
reaping in Tx fastpath itself.
2) In ce_per_engine_service_fast check for more Rx packets after
packet processing.
3) Make stub functions as static inline for non-fastpath enabled case.
