start change to progspace independence
This patch starts changing minimal symbols to be independent of the
program space.
Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS
and changes all the code to use it. This is needed so we can change
gdb to apply the section offset when a minsym's address is computed,
as opposed to baking the offsets into the symbol itself.
A few spots still need the unrelocated address. For these, we
introduce MSYMBOL_VALUE_RAW_ADDRESS.
As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS,
which computes the address of a bound minimal symbol. This just does
the obvious thing with the fields.
Note that this change does not actually enable program space
independence. That requires more changes to gdb. However, to ensure
that these changes compile properly, this patch does add the needed
section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has
no effect at runtime by multiplying the offset by 0.

use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym. This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.
Note that this changes even those functions that ostensibly search a
single objfile. That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.
The bulk of this patch is mechanical.

start change to progspace independence
This patch starts changing minimal symbols to be independent of the
program space.
Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS
and changes all the code to use it. This is needed so we can change
gdb to apply the section offset when a minsym's address is computed,
as opposed to baking the offsets into the symbol itself.
A few spots still need the unrelocated address. For these, we
introduce MSYMBOL_VALUE_RAW_ADDRESS.
As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS,
which computes the address of a bound minimal symbol. This just does
the obvious thing with the fields.
Note that this change does not actually enable program space
independence. That requires more changes to gdb. However, to ensure
that these changes compile properly, this patch does add the needed
section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has
no effect at runtime by multiplying the offset by 0.
