- support float version of convolution
- support the CHW tensor layout
following function prototypes are added:
- arm_convolve_CHW_f32_basic_nonsquare()
- arm_convolve_CHW_q15_basic_nonsquare()
- arm_convolve_CHW_q7_basic_nonsquare()
- arm_nn_CHW_mat_mult_kernel_q7_q15()
NOTE:this patch will be contributed to SMSIS and reverted later from NuttX

Sometimes netcat in server mode crashed with "psock_accept: ERROR: si_accept failed: -9".
And sometimes it crashed with "up_assert: Assertion failed at file:inet/inet_sockif.c line: 841 task: netcat".
This example demonstrate swap between two valid images. Instructions
are available at readme.md file inside project directory.

the CMSIS NN software library is a collection of efficient neural
network kernels developed to maximize the performance and minimize
the memory footprint of neural networks on Cortex-M processor cores.
Project https://github.com/ARM-software/CMSIS_5
The library is divided into a number of functions each covering
a specific category:
Convolution Functions
Activation Functions
Fully-connected Layer Functions
SVDF Layer Functions
Pooling Functions
Softmax Functions
Basic math Functions
The library has separate functions for operating on different weight
and activation data types including 8-bit integers (q7_t) and 16-bit
integers (q15_t). The descrition of the kernels are included in the
function description.

Summary:
- I noticed that 'make import' failed due to recent changes in nuttx
- This commit fixes this issue by adding logic for -lm
- Also applies the same style for -lgcc
Impact:
- CONFIG_BUILD_KERNEL=y only
Testing:
- Build (mkimport, make import) with sama5d4-ek:knsh

This is a runtime library for inference Neural Network created
by Neural Network Libraries.
Project git: https://github.com/sony/nnabla-c-runtime
It is almost independent from external libraries(depends on C
standard math library) and is written in Pure C (C99).
It has been developed with priority over readability rather than
performance, making it ideal for learning and porting.
It adopts an extensible architecture, and you can use the function
you implemented yourself as necessary for applications that need performance.

Summary:
- I noticed that applications made by 'make import' contain
undefined symbols such as printf for CONFIG_BUILD_KERNEL=y
- This commit fixes this issue by adding user libraries.
- Also, this commit generates libapps.a which is used for init
Impact:
- CONFIG_BUILD_KERNEL=y only
Testing:
- Build (mkimport, make import) with sama5d4-ek:knsh

Summary:
- I noticed that 'make export' does not work with swama5d4-ek:knsh
- This commit fixes this issue by always creating the registry directory
but not copying pdat files for CONFIG_BUILD_KERNEL=y
- This commit also fixes the delimiter issue on Windows
- NOTE: nuttx needs to be updated as well
Impact:
- CONFIG_BUILD_KERNEL=y only
Testing:
- Build (make and make export) with sama5d-ek:knsh

This option enables using sendfile() in ftpc binary transfer mode of PUT operation.
If the option is enabled but ASCII transfer mode is activated,
ftpc falls back to the combination of read() and write().
Using sendfile() provides a higher performance compared to
the combination of read() and write().
Also this option is useful for testing / debugging tcp_sendfile()
functionality of NuttX TCP/IP stack.
