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.

Daniel Malea d01b2953fa Resolve printf formatting warnings on Linux:
- use macros from inttypes.h for format strings instead of OS-specific types

Greg Clayton 86edbf41d1 Cleaned up many error codes. For any who is filling in error strings into
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.

Greg Clayton f3ef3d2af9 Added new lldb_private::Process memory read/write functions to stop a bunch
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.

Greg Clayton e376938e93 Added the ability to sign extend a Scalar at any bit position for integer
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.
