The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.
But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.
So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

In --stdio we turn off color output when the output is not a tty,
which is not always desirable, for instance, in:
perf annotate | more
the 'more' tool is perfectly capable of processing the escape sequences
for colored output.
Allow using the existing logic for .perfconfig's "color.ui" to be used
from the command line by providing a stdio__config_color() helper, that
will be used by annotate and report in follow up patches.

Introducing allocation callbacks, that allows to extend current
hist_entry object into objects with special needs without polluting the
current hist_entry object.

Move the 'struct hist_entry' initialization code to a separate function.
It'll be useful and more clear for the following patches that introduce
allocation callbacks.
Releasing the hist_entry object in hist_entry__new function
(where it's allocated) rather than in hist_entry__init.

Noticed by the build system, that emitted this warning:
Warning: x86_64's syscall_64.tbl differs from kernel
This was due to the wiring up of the recently added preadv2 & pwritev2
syscalls to the compat code, which hadn't been done by the patch
introducing those syscalls: 4babf2c5ef ("x86: wire up preadv2 and
pwritev2").
The patch doing the compat wiring was:
482dd2ef12 ("x86/syscalls: Wire up compat readv2/writev2 syscalls")
This just silences the perf build warning, as compat syscalls still
can't be supported in 'perf trace´ due to limitations in the
raw_syscalls:sys_{enter,exit} tracepoints it relies on.

NDK version 11(oldest supported version) and NDK version 12(current
version).
