The kernel-doc script identified a large number of documentation
issues in the QDF. A series of patches has already fixed many of the
issues, so fix most of the remaining ones.
Note that the QDF IPA abstraction still has issues, but it is under
rework, so not trying to clean it up until after the rework is
complete.

Currently, when an unpermitted character is added to ini, driver
flags as an unknown config item and continues parsing. This could
be an issue. Change is to return error when invalid character is
parsed in ini.

INI parameters parsing can fail because of fail to read INI file or
failed to parse at least one parameter. In some scenarios, driver should
assert if parsing is failed for atleast one INI parameter.
To differentiate these two failures, return different error status
values.

spin_is_locked() provided by kernel has statement that we should not
rely heavily on the return value, it only tells that the spinlock is
seen to be locked, not that it is locked on your CPU.
Further, on CONFIG_SMP=n builds with CONFIG_DEBUG_SPINLOCK=n, the
return value is always 0.
So we should not use QDF_BUG to test/assert its return value, only be
used for debugging purpose.

The function qdf_ini_parse returns QDF_STATUS as SUCCESS even if no
fields are read from the ini file. Because of this even if the
ini file is corrupted and no values are read from it the function
still returns SUCCESS.
So, to avoid that and ensure that the ini file is not corrupted,
add a variable ini_read_count to count the number of fields read
from the ini file and return SUCCESS only if its value is not zero.

A common problem in any C code base is the proper management of various
resources, such as memory allocations, timers, works, locks, etc. To
that end, WLAN has added various one-off leak tracking features for
different resources over the years, to great benefit. However, this
approach is tedious, and prone to copy/paste and fix propagation issues,
making maintaining these various tracking features onerous.
Add a generic leak tracking data structure to WLAN for general use,
which implements these tracking logics. This will allow the various
resource tracking features to leverage this shared implementation for
ease of maintenance. Build on the hash table implementation added as
part of I7f5fc0c59ed220bde43044e7013b3c8573f1bf39.

Due to a limitation in the memory leak detection logic when qdf_flex_mem
was written, qdf_flex_mem_release() was necessary to free any
dynamically allocated memory in the qdf_flex_mem_pool during certain
points in the WLAN driver lifecycle. This was done to avoid flagging any
dynamically allocated qdf_flex_mem_segments as false positive leaks
when the memory domains were changed and leak checking was performed.
With the introduction of qdf_talloc(), this workaround is no longer
required. Replace the calls to qdf_mem_malloc/free with qdf_talloc/free,
and remove qdf_flex_mem_release() altogether.

Add APIs for t(ree) alloc(ated) memory management.
These APIs allocate memory like malloc, but track those allocations via
a parent-child relationship, or tree. If the parent is freed while it
still has children, a panic will be triggered. This effectively gives
you the ability to limit the lifetime of an allocation by ensuring the
child allocation lifetime will be strictly less than the parent
allocation lifetime.
