The midifile library used by the playmidi1 program dates from 1989, and
used pre-ANSI function definitions and prototypes. GCC 15 now defaults
to C23 where () means the same as (void) in prototypes, which causes
type mismatch errors.
Update the code to use ANSI function definitions and prototypes, so
it'll compile happily as anything from ANSI C to C23. This revealed that
playmidi1's do_tempo had the wrong argument type, so correct that as
well.

It's a simple filtering application that just haves the incoming note

It is useful to use the math expressions for the values in configuration.
This patch adds a simple expression evaluation routines (integer only).
The syntax is simplified unix shell (bash) style.
Examples:
$[1 + 1]
$[$[2 + 2] / $var1]
$[0xa0 | 0x05]
As a bonus, the variable substitutions were more abstracted.
The function snd_config_expand_custom() was introduced to be used
for example in the topology pre-precessor.

We hide the internal data transfers using the data frames. Rename
the snd_rawmidi_framing enum to snd_rawmidi_read_mode to make
API more straight and understandable.
Signed-off-by: Jaroslav Kysela <perex@perex.cz>
The frame structure is a bit internal thing for the kernel
data transfer implementation. Introduce snd_rawmidi_tread()
function which is straight for the application usage and hides
the framing data transfers (kernel space API).
The current code implements the read cache and does the merging
of the frame reads with the similar timestamps (opposite
to the kernel data split for big chunks).
If the application wants to use super-duper-lighting-fast reads,
the snd_rawmidi_read() may be used, but the structure must be
defined on it's own, because this mechanism is not preferred
and unsupported.

Events sent by external clients subscribed to the input port are not
timestamped.
This inconsistent behavior may surprise newbies who look at seq-decoder as
a reference example.
See the example below using "vkeybd --addr 128:0" to connect to seq-decoder,
the events sent by vkeybd are on a different queue with no timestamps:
...
EVENT>>> Type = 66, flags = 0x0, time = 0 ticks
Source = 0.1, dest = 128.0, queue = 253
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 66, flags = 0x1, time = 4.829712627
Source = 0.1, dest = 128.0, queue = 0
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 10, flags = 0x0, time = 0 ticks
Source = 129.0, dest = 128.0, queue = 253
Event = Controller; ch=0, param=0, value=0
EVENT>>> Type = 11, flags = 0x0, time = 0 ticks
Source = 129.0, dest = 128.0, queue = 253
Event = Program Change; ch=0, program=0
...
After the change events are on the main queue and are timestamped:
...
EVENT>>> Type = 66, flags = 0x1, time = 4.280907223
Source = 0.1, dest = 128.0, queue = 0
Event = Port Subscribed; 129:0 -> 128:0

At kernel v4.14, in initial state, elements on user-defined sets have
write-only flag. When applications write TLV data, then the elements
get readable flag and the TLV data is available. Originally TLV data
is shared by elements in the same set, thus events are generated for
all of elements in the set by the write operation.

Currently, this test program has a bug related to dimension information.
When testing an element set with byte type, the program adds 512 members
to an element. This is a maximum number permitted for this type.
On the other hand, dimension information of the elements consists of
[8, 4, 8, 4]. Calculated members in the multi-dimensional matrix is 1024.
This should be less than 512.
