YAMAMOTO Takashi e7156be066 Change the defaults of stack size configs to DEFAULT_TASK_STACKSIZE
This commit changes only ones with the default 2048 and
leaves the others.
E.g. this leaves SYSTEM_RAMTEST_STACKSIZE, whose default is 1024.
I guess those need to be inspected one-by-one.

tcpblaster Performance Test Example
===================================

To set up, do `make menuconfig` and select the Apps > Examples > tcpblaster. By default, nuttx will the be the client
which sends data; and the host computer (Linux, macOS, or Windows) will be the server.

Set up networking so the nuttx computer can ping the host, and the host can ping nuttx. Now you are ready to run the
test.

On host:

    $ ./tcpserver
    Binding to IPv4 Address: 00000000
    server: Accepting connections on port 5471

On nuttx:

    nsh> tcpclient
    Connecting to IPv4 Address: 0100000a
    client: Connected
    [2014-07-31 00:16:15.000] 0: Sent 200 4096-byte buffers:    800.0 KB (avg   4.0 KB) in   0.18 seconds ( 4444.4 KB/second)

Now on the host you should see something like:

    $ ./tcpserver
    Binding to IPv4 Address: 00000000
    server: Accepting connections on port 5471
    server: Connection accepted -- receiving
    [2020-02-22 16:17:07.000] 0: Received 200 buffers:   502.9 KB (buffer average size:   2.5 KB) in   0.12 seconds ( 4194.8 KB/second)
    [2020-02-22 16:17:07.000] 1: Received 200 buffers:   393.1 KB (buffer average size:   2.0 KB) in   0.09 seconds ( 4299.4 KB/second)


This will tell you the link speed in KB/sec  kilobytes per second. If you want kilobits, multiply by 8.

You can use the `make menuconfig` to reverse the setup, and have nuttx be the server, and the host be the client. If you
do that, start the server first (nuttx), then start the client (host).
