FreeBSD insists that <sys/types.h> be included before <netinet/in.h> and that <netinet/in.h> be included before <arpa/inet.h>. This adds guards to the "sparse" headers to yield a warning if this order is violated. This commit also adjusts the order of many #includes to suit this requirement.

# The following explanation may help to understand the use of the
|
|
# version number fields: current, revision, and age.
|
|
#
|
|
# Consider that there are three possible kinds of reactions from
|
|
# users of your library to changes in a shared library:
|
|
#
|
|
# 1. Programs using the previous version may use the new version as drop-in
|
|
# replacement, and programs using the new version can also work with the
|
|
# previous one. In other words, no recompiling nor relinking is needed.
|
|
# In short, there are no changes to any symbols, no symbols removed,
|
|
# and no symbols added. In this case, bump revision only, don't touch
|
|
# current nor age.
|
|
#
|
|
# 2. Programs using the previous version may use the new version as drop-in
|
|
# replacement, but programs using the new version may use APIs not
|
|
# present in the previous one. In other words, new symbols have been
|
|
# added and a program linking against the new version may fail with
|
|
# "unresolved symbols." If linking against the old version at runtime:
|
|
# set revision to 0, bump current and age.
|
|
#
|
|
# 3. Programs may need to be changed, recompiled, relinked in order to use
|
|
# the new version. This is the case when symbols have been modified or
|
|
# deleted. Bump current, set revision and age to 0.
