Added any() and all() value expression macros

any() matches an expression against every post in a transaction or
account, and returns true if any of them are true.  all() tests if all
are true.  For example:

  ledger -l 'account =~ /Expense/ & any(account =~ /MasterCard/)' reg

This reports every posting affecting an Expense account (regex match),
but only if some other posting in the same transaction affects the
MasterCard account.

Both functions also take a second boolean argument.  If it is false, the
"source" posting is not considered.  For example:

  ledger -l 'any(/x/, false)'

This matches any posting where a *different* posting in the same
transaction contains the letter 'x'.
