lets a ValueObject's contents be set from raw
data. This has certain limitations (notably,
registers can only be set to data that is as
large as the register) but will be useful for
the new Materializer.
I also exposed this interface through SBValue.
I have added a testcase that exercises various
special cases of SBValue::SetData().

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible
Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

of duplicated code from appearing all over LLDB:
lldb::addr_t
Process::ReadPointerFromMemory (lldb::addr_t vm_addr, Error &error);
bool
Process::WritePointerToMemory (lldb::addr_t vm_addr, lldb::addr_t ptr_value, Error &error);
size_t
Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error);
size_t
Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error);
in lldb_private::Process the following functions were renamed:
From:
uint64_t
Process::ReadUnsignedInteger (lldb::addr_t load_addr,
size_t byte_size,
Error &error);
To:
uint64_t
Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr,
size_t byte_size,
uint64_t fail_value,
Error &error);
Cleaned up a lot of code that was manually doing what the above functions do
to use the functions listed above.
Added the ability to get a scalar value as a buffer that can be written down
to a process (byte swapping the Scalar value if needed):
uint32_t
Scalar::GetAsMemoryData (void *dst,
uint32_t dst_len,
lldb::ByteOrder dst_byte_order,
Error &error) const;
The "dst_len" can be smaller that the size of the scalar and the least
significant bytes will be written. "dst_len" can also be larger and the
most significant bytes will be padded with zeroes.
Centralized the code that adds or removes address bits for callable and opcode
addresses into lldb_private::Target:
lldb::addr_t
Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
lldb::addr_t
Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
All necessary lldb_private::Address functions now use the target versions so
changes should only need to happen in one place if anything needs updating.
Fixed up a lot of places that were calling :
addr_t
Address::GetLoadAddress(Target*);
to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress()
as needed. There were many places in the breakpoint code where things could
go wrong for ARM if these weren't used.

types.
Added the abilty to set a RegisterValue type via accessor and enum.
Added the ability to read arguments for a function for ARM if you are on the
first instruction in ABIMacOSX_arm.
Fixed an issue where a file descriptor becoming invalid could cause an
inifnite loop spin in the libedit thread.
