This rationalises atari platform user of headers and squashes a lot of
warnings. Should not be viewed as real maintenance, more that it was
getting in the way of fixing real core header issues.
The wallclock() API uses gettimeofday which can be affected by the the
systems clock being changed etc. The curl fetcher usage of this API is
to generate a timing delta and does not cope with the gettimeofday
issues.
This changes the fetcher to use the nsutils library monotonic time
function which does not suffer from the issues with gettimeofday.
The config header was causing many source files to unecessarily
include the dirent headers causing extra dependancies. This has been
fixed by providing a utility dirent header that provides a common API
across all platforms while removing the unecessary dirent header usage.
The utils header is a large collection of functionality for several
system headers and API. This splits out the ones from sys/time.h into
a separate header reducing the need for many unconnected source files
to include the system header unecessarily.
The utility configuration header dragged in a number of bsd sockets
and related API as a side effect of setting up the configuration. By
splitting the header and API setup into a separate header only the
small number of places that need the functionality explitly include
it.
The update to remove curl usage from urldb must pull in the utility
config header instead to get inet_aton and such or compoles on some
platforms fail.
currently NetSurf uses curl_getdate to convert textural date and time
strings into seconds since epoch. It is betetr to move this
functionality to a utility function so curl_getdate can easily be
replaced if required.
When the operations tables were created the browser table was renamed
to miscellaneous except the actual rename patch was never applied,
this fixes that situation.
