[Qemu-devel] [RFC v6 0/2] monitor: add memory search commands s, sp

[hw.claudio@gmail.com]

From: Claudio Fontana <claudio.fontana@huawei.com>

This is the latest iteration of the memory search patch,
including a trivial replacement for the memmem function for systems
which don't provide one (notably Windows).

It detects the presence of memmem in configure and sets CONFIG_MEMMEM,
providing a trivial implementation for the !CONFIG_MEMMEM case.

The new code is MIT licensed, following usage of other files in the same
directory dealing with replacement functions (osdep, oslib, getauxval etc),
and to maximize reusability.

I have tested this in both CONFIG_MEMMEM defined/undefined scenarios,
but more feedback and testing is welcome of course.

changes from v5:
dropped the import from gnulib and implemented a trivial replacement.

changes from v4:
made into a series of two patches.
Introduced a memmem replacement function (import from gnulib)
and detection code in configure.

changes from v3:
initialize pointer variable to NULL to finally get rid of spurious warning

changes from v2:
move code to try to address spurious warning

changes from v1:
make checkpatch happy by adding braces here and there.
