Use `errno` instead, which is icky, but given that all of the failure
modes are from POSIX I/O functions, it’s at least in keeping with them.
This is a major API break.

Another step towards dropping GLib as a dependency of
libsysprof-capture.
Unlike the previous commit which replaced GLib integer types with the
bitwise equivalent C standard types, `stdbool` is potentially a different
width from `gboolean`, so this is an ABI break.
It therefore involves some changes to callback functions in the tests
and tools, and in libsysprof.

In preparation for dropping the GLib dependency from libsysprof-capture,
move the autocleanup definitions up to libsysprof. Add a new header for
them.
This is slightly awkward in the tools, which depend on
libsysprof-capture but not libsysprof. Rather than make them depend on
libsysprof (which might be disabled at configure time), include the
`sysprof-capture-autocleanups.h` file between source directories.
`SYSPROF_COMPILATION` needs to be defined for this to work.
