Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
We should have been doing this all along, but we get away with it
on Linux where libusb can do everything with fds, and we get away
with it for many drivers that have a short timeout on their events.
On Windows though, handling this correctly is essential.
Fixes bug #343.
Commit 5801d558 replaced g_slist_copy_deep() by some incorrect code
that actually leaks the newly allocated memory, instead of doing
a deep copy.
This new version should be more correct, more concise, and it fixes
the following warning:
src/session.c: In function 'sr_packet_copy':
src/session.c:1025:38: warning: passing argument 2 of 'g_slist_foreach' from incompatible pointer type [-Wincompatible-pointer-types]

By avoiding g_slist_copy_deep() for now, we can easily allow libsigrok
to build against glib 2.32 (less hassle for users of stable/older
distros or OSes).
Use g_malloc0() for small allocations and assume they always
succeed. Simplify error handling in a few places accordingly.
Don't always sanity-check parameters for non-public (SR_PRIV)
functions, we require the developers to invoke them correctly.
This allows further error handling simplifications.
