There is a big issue to validate all possible configuration paths.
Let create ucm2/ucm.conf file which describe the lookups. It may
be also customized later to follow the kernel-side development.

Syntax:
DefineRegex.VariableName {
String "something to match"
Regex "(me)thi(ng)"
}
Result:
- configuration variable "VariableName" is equal to "mething"
- configuration variable "VariableName1" is equal to "me"
- configuration variable "VariableName2" is equal to "ng"
Notes:
The "Flags" string in the DefineRegex compound may specify
the compilation flags (e = extended, i = ignore case,
s = no substitutes, n = newline). See 'man 3 regex' for
more details.

It may be useful for the library files to use the runtime configuration
variables.
Example:
Define.Var1 "hw:${CardId},2"
Value.PlaybackPCM "${var:Var1}"

We need a way to set the SectionOnce at first before SectionDefaults.
It also does not make sense to run SectionDefaults when the API is
used only to query for values or so.
Execute the SectionDefaults commands only when the first verb
is set (before the verb specific commands).

The recent gcc warning indicates the uninitialized variable commit_err:
pcm_rate.c:1104:6: warning: ‘commit_err’ may be used uninitialized in this function [-Wmaybe-uninitialized]
if (commit_err < 0)

Add a proper initialization to commit_err.

We've got a gcc warning:
pcm_rate.c: In function ‘snd_pcm_rate_drain’:
pcm_rate.c:1090:19: warning: suggest parentheses around comparison in operand of ‘&’ [-Wparentheses]
if (pcm->mode & SND_PCM_NONBLOCK != 0) {

Drop the zero comparison for fixing the warning and for simplicity.

It seems that we have regressions for pcm.front (some
applications are using this device also for the default
raw input). Change the description and allow both
directions.

Newer versions of GCC (> 5.0) accept that ebx is declared
in the clobber list even in PIC mode. Meanwhile, even
unlikely, the compiler may use ebx as base address of
one of the memory entry, making subsequent access to
them unreliable ('size', 'dst_step', 'src_step', 'sum_step').
Adding ebx in the clobber solves the problem.
By the way, the entry 'old_ebx' is no longer required.

- add mm0 in the clobber list if the compiler
is aware of the mmx technology;
- otherwise, add the mmx aliased x87 floating point
registers in the clobbers;
- the configure now checks if the compiler is aware of
the MMX technology.
The compiler assumes none of the mmx or x87 registers are used
by the function. If it chooses to store some data in them, they
will be overwritten by the chunk.
Recall that any mmx instruction invalidate the whole set of
x87 floating point registers.
Note: currently does not impact the binary output.

- move 'size' and 'old_ebx' in the output section
since they are clobbered;
- add the "memory" clobber since input pointers
are accessed;
- (minor) add the "cc" clobber since flags are
clobbered.
The compiler is missing some dataflow information
about the execution of the assembly chunks.
For instance, it assumes that 'size' remains unchanged
and that no input pointer is accessed.
The compiler optimizer may take advantage of these
assumption and produce a wrong code.
Note: currently produces the same binary output.

The draining function of the rate plugin does not handle properly the
SND_PCM_NONBLOCK case. It can write data to the slave plugin each time the
function is called, but does not update its internal state in order to
reach a stopping condition. Use a last_commit_ptr workaround to reach such
condition.

It should be safe to change this as correct values with int would be 0
or 1 and bool parser handles them correctly.

In pcms using direct plugins (dmix/dsnoop/dshare), the timestamp type could
be different from the terminating hw plugin, then the kernel driver.
Be sure such pcms have plugins using consistently the same timestamp type.
