We need clang support for the testbench therefore the following changes
are needed
remove -ftree-vectorizer-verbose since its deprecated in gcc and not
supported in clang
remove =3 from -Wimplicit-fallthrough=3 since 3 is the default level
anyways

free() system call frees the memory space pointed to by
ptr, which must have been returned by previous call to
malloc(), calloc() or realloc().
Now, when incrementing the array pointer, we may have
exceeded the actual allocated size. If we do pointer arithmetic
and subtract size from the array pointer, we may not point to
the actual location returned by malloc().
This patch makes sure that when we do pointer arithmetic on array,
the array's value at the end would be same as the one returned
by malloc.

This patch uses the functionality added by the c9e090ccf3 commit
to check for array size mismatch in various components.
Not doing so may result in cases, where we try to write into the
space not allocated leading to segmentation fault.

This patch uses the functionality added by the c9e090ccf3 commit
to check for array size mismatch in components.
Since, the components are in places other than tplg_parser, the
function which checks for the mismatch has been made an external
function from a static one. The function declaration has been
added to the tplg_parser header files, so that the function can
be used by any code which needs array size checks in components.

There may be a situation where size of all elements of the
snd_tplg_vendor_array is greater than the private data size.
If we take a look at array structure
struct snd_soc_tplg_vendor_array {
__le32 size; /* size in bytes of the array, including all elements */
__le32 type; /* SND_SOC_TPLG_TUPLE_TYPE_ */
__le32 num_elems; /* number of elements in array */
union {
struct snd_soc_tplg_vendor_uuid_elem uuid[0];
struct snd_soc_tplg_vendor_value_elem value[0];
struct snd_soc_tplg_vendor_string_elem string[0];
};
} __attribute__((packed));
and assume of private data size is size.
If num_elems * sizeof(..._elem) > size occurs, this is bad
because, we first try to allocate _size_ bytes via malloc to array
pointer. Since the num_elems * sizeof(..._elem) is greater than
size, we get a segmentation fault when we try to memcpy the
remaining size in the subsequent functions (read tplg_read_array()).
We fix this problem by checking for whether array size falls
within the bounds of private data size.

In order to run multi-output component playback by testbench, this patch
supports multiple output file mode on running testbench. Argument "-o" is
modified to accept specifying up to 4 filenames delimited by comma,
e.g. "-o output1,output2,..."
Moreover, debug messages in tplg_parser/tplg_parser.c is refined for
demonstrating multiple pipelines better.

Before accessing the contents of the parameter pointer of the
function, check if the pointer is NULL. Else, it may lead to
segmentation fault.

When an error is occurred when loading the widget, the memory
allocated is not freed properly. This results in memory leaks.
Avoid these memory leaks by freeing the allocated memory before
exiting the function by returning error value.

This patch replaces the manually set error codes with errno that
is set to exact fail reason like ENOMEM etc. by these functions. The
missing return code checks for fseek() calls are added.
Include of header errno.h is added to topology.c. The order of
include statements is fixed.

In some topologies there is a component tokens array after buffer
tokens array for buffer widget. Since the earlier code version was
able to handle only single array and did not skip the remaining it
caused the remaining topology parsing to go out of sync and fail.
This patch changes the vendor array parsing to be similar as for PCM
widget that already had capability to handle several arrays. The core
id is retrieved if present in topology and passed via IPC.

This patch adds to testbench capability to run pipelines with EQ_IIR
and EQ_FIR components. The component is configured with the topology
embedded configuration blob when instantiated with new().
The load of volume component has been enhanced to parse volume tokens and
compute the min and max volume parameters.
The topology parsing and component library load has been changed to
support processing component load and extracting of control private
data. The testbench build has been changed to create libraries
for EQ components.
The testbench command line parsing has been improved to return
error for invalid library request.

This patch fixes the fail to execute tests due to recent pipeline
updates. Now the fileread and filewrite component is instantiated
as host or DAI depending on stream direction. The DAI file component
is added the capability to report HW stream parameters. In testbench
case the stream parameters originate from command line parameters.
The file params() handling is updated to be similar as in other
components to successfully propagate the parameters.
The added capture pipelines support is not fully functional and will
be fixed later.
The testbench cleanup includes elimination of global variables for
certain component ids. The needed misc parameters were added to
testbench parameters struct that is passed through most topology
parsing functions.

The topology parser in testbench can be re-used for
the other applications like the fuzzer. In order to
accomplish this, this commit does the following:
1. Separate the topology parser into a separate project
(tplg_parser) which implements the callbacks for parsing
all the components in topology.
2. Add support for parsing new components such as host
pcm, dai and mixer
3. Include the topology parser as an external project
in the testbench.
