doing this breaks with older kernels as it will pick a set without
and update callback.

Rework grammar to skip the 'name' token after 'meter' for named meters.
For consistency with sets and maps in terms of syntax.

According to bugzilla 1137: "flow tables" should not be syntactically
unique.
"Flow tables are always named, but they don't conform to the way sets,
maps, and dictionaries work in terms of "add" and "delete" and all that.
They are also "flow tables" instead of one word like "flows" or
"throttle" or something.
It seems weird to just have these break the syntactic expectations."
Personally, I never liked the reference to "table" since we have very
specific semantics in terms of what a "table" is netfilter for long
time.
This patch promotes "meter" as the new keyword. The former syntax is
still accepted for a while, just to reduce chances of breaking things.
At some point the former syntax will just be removed.

Anders reports that:
# nft add rule ip6 filter postrouting \
flow table acct_out \{ meta iif . ip6 saddr timeout 600s counter \}
while the opposite doesn't work:
# nft add rule ip6 filter postrouting \
flow table acct_out \{ ip6 saddr . meta iif timeout 600s counter \}
netlink_gen_flow_stmt() relies on the flow table key, that is expressed
as a set element. Use the set element key instead to skip the set
element wrap, otherwise get_register() abort execution:
nft: netlink_linearize.c:650: netlink_gen_expr: Assertion `dreg < ctx->reg_low' failed.
